Presentation Title: Solar combined heating, cooling and power systems based on hybrid PV-thermal technology
Abstract: By 2050, solar technologies are projected to deliver the majority of the world’s electricity. Although solar energy can be used to provide both heat and electrical power, most solar panels are designed for only one of these purposes. In particular, photovoltaic (PV) panels are typically less than 20% efficient in delivering electricity from the sun’s incident energy. At the same time, it is well known that PV cells experience a deterioration in performance (efficiency) when they are operated at higher temperatures, and that this leads to high losses especially when the solar resource is at its highest. For example, a drop in PV cell efficiency of up to 20% can be expected when the PV cells reach operating temperatures of ~60-70 °C, which is easily experienced in hot climates.
This performance loss has motivated the development of so-called ‘hybrid’ PV-thermal (PV-T) solar collector technology, which combines PV modules with a contacting fluid (gas or liquid) flow in various different geometries and configurations. Here, the fluid is used to cool the PV cells and, therefore, to increase their electrical efficiency, while delivering a potentially useful thermal output (hot fluid stream) from the collector, which offers some advantages when space is at a premium and there is demand for both heat and power. PV-T collectors have been shown to be a highly efficient technology, capable of achieving system efficiencies (electrical plus thermal) in excess of 70%.
By far the most common use of the thermal-energy output from PV-T systems (in fact most solar-thermal collector technologies) is to provide hot water at 50-60 °C for households or commercial use. However, a wide range of opportunities arise at higher temperatures when additional power-generation cycles (e.g., with organic Rankine cycles, thermoelectric generators, amongst other) or thermally-driven cooling technologies (e.g., with desiccant, ad/absorption refrigeration cycles, amongst other) can be integrated with solar (including PV-T) collectors into wider multi/polygeneration systems. These additional options become viable at temperatures typically above ~80 °C, and importantly, become increasingly efficient at progressively higher temperatures. In standard PV-T collector designs, however, the electrical and thermal outputs are traded-off each other, since any effort to collect additional thermal energy or to increase the temperature of that energy leads to an electrical loss. This has led recently to the proposal of collector designs that can deliver useful heat at a high temperature while not sacrificing the electricity output. In this talk we will present conventional and such advanced PV-T collector designs, their underpinning principles, discuss the challenges and opportunities of further developing this technology, and of integrating it within wider solar-energy systems capable of the affordable provision of cooling, heating and power.

Presentation Title: Role of Lean Education in Preparing Future Workforce: Closing the Academic and Professional Gap
Abstract: Academic and professional worlds are kept apart from working together by an invisible barrier. Nevertheless, the academia is preparing the future professionals and to achieve this preparation, a tuning between professional needs and academic teaching is critical. Though the academia has an important role in forecasting the future needs, the professionals, many times, are in better conditions to forecast due to their proximity to the market and its needs. So a joint work must be done between these two worlds. Lean Education derives from a methodology that emerged in the industry, and nowadays is spread to all industries and services, including the education services, not only as a way to improve these services but more importantly, as a pedagogical platform to innovate the learners’ curricula and better prepare them for the professional world. Lean education allows development of competencies such as systems thinking, critical analysis, sustainability and ethical issues, assessment challenges of the overall performance of a system as opposed to the detailed functions of a component, as well as establishing criteria for, and transparency of decision making. This plenary addresses the above deficiencies from a holistic perspective, accounting for issues in communications, teamwork across discipline and geographic borders, and project/design status visualization. Lean Education’s role as a holistic perspective and as a curricular innovation capable of developing the competencies missing in the current engineering curricula that bridge the gap between the academic and professional worlds. The talk covers sustainability and systems concepts of Lean Education, identification of strategies and weaknesses in current curricula, competencies and skills needed to an organizational health and Lean Education’s capability in providing content and competency mastery pulled by stakeholders (society, employers, faculty, students).

Title: Using Uncertainty Quantiﬁcation with HPC to Reconcile Models and Measurements
Abstract: Bayesian methods for uncertainty quantiﬁcation (UQ) provide the opportunity to identify model form uncertainty in both measurements and models. Under sponsorship of the US DOE NNSA we have used HPC (10 - 250 thousand cores) with scalable large eddy simulations (LES) for utility scale (100 - 1000 MW) particle-laden pulverized coal and biomass power boilers. We have found that these UQ-methods have allowed us to use data from models and measurements to extrapolate from laboratory scale experiments to full-scale predictions. The resulting Bayesian posterior predictive includes the effect of uncertainty from model parameters, scenario parameters, and model form uncertainty in both the instrument models and the predictive physics-based LES models.

Presentation Title: Using Additive Manufacturing to Advance Designs in Convective Cooling
Abstract: Recent technological advances in the field of additive manufacturing (AM) have widened the design space for complex convective cooling designs. Using additive manufacturing allows for increasingly small and complex geometries to be fabricated with little increase in time or cost. The opportunity for heat transfer engineers is to exploit the use of additive manufacturing in re-thinking how to optimize cooling schemes for components, or generate novel heat transfer surfaces. Interesting roughness features result when using additive manufacturing, which are a strong function of the build parameters. The inherent roughness using additive manufacturing can, in fact, be used to improve convective heat transfer beyond that of highly engineered surfaces. New design tools can generate components with enhanced performance, although further improvements in accounting for roughness are needed.

Presentation Title: Nanowarming for Regenerative Medicine
Abstract: This talk will explore the underlying physics and advantages of nanoparticle-based rewarming technologies for regenerative medicine. Gold and iron oxide nanoparticles have unique and tunable properties that allow transduction of optical or radiofrequency (RF) electromagnetic fields to affect heating of biomaterials at multiple scales (1 µL droplets to L containers). Indeed, both nanoparticle types have a long history of use for controlled heating in the treatment of cancer. This talk will explore the use of nanoparticle heating for a new application entitled “nanowarming,” which allows both rapid and uniform rewarming of vitrified (i.e. cryopreserved) biomaterials back from the cryogenic state, thereby avoiding crystallization and cracking failures. This warming, which can range from 100s °C/min with iron oxide RF heating to 10,000,000 °C/min with laser gold warming, addresses a rewarming technology bottleneck for vitrified large (i.e. tissues and organs) and small systems (i.e. embryos and oocytes). New capabilities in cell, tissue, and rodent organ cryopreservation, including the first zebrafish embryo cryopreservation yielding live and reproducing fish, will be presented. In summary, this talk demonstrates the growing opportunities for nanoparticle heating in regenerative medicine.

Abstract: An integrated circuit achieves its function by integrating dissimilar components, and so does a living organ. Soft materials—tissues, elastomers, hydrogels, and ionogels—are under intense development for immediate and far-reaching applications. Examples include tissue regeneration, synthetic biology, drug delivery, soft robots, ionotronics, bioelectronics, skin-attached and implanted devices, active textiles, as well as wearable and washable devices. Nearly all applications require the integration of dissimilar soft materials. This talk describes several recent examples of integrated soft materials that achieve unusual functions.

Presentation Title: Material and microstructural features that prompt sub-crystalline localization in polycrystalline high-performance alloys
Abstract: Improved prediction of the behavior of materials under the complex loading conditions encountered in structural components is critical to ensure reliable, long-term performance and to guide the design of new materials along high controlled processing paths. However, a major challenge for structural materials is the strong dependence of the intrinsic plastic deformation processes on material structure, with important features at the nanoscale, microscale and mm-scale in most classes of metallic materials. Deformation processes are typically highly heterogeneous, propagating through complex microstructure-dominated networks, ultimately resulting in local damage and failure of the part. Cyclic and monotonic loading are performed on a number of high-performance alloys, such as high strength titanium aerospace alloy and Ni-based superalloys. Using a combination of in-situ deformation DIC and synchrotron measurements, 3D microstructural characterization, and 3D crystal plasticity based computational modeling, we investigate the micromechanical and microstructural factors leading to strain localization and subsequent slip band initiation. This suite of techniques altogether enables full-field measurement and modeling of the plastic and elastic field at the surface and in the bulk of the specimen. The analysis focuses on the coupled role of elastic anisotropy, grain neighborhoods, and grain shape and size in determining the location of the exceptionally preferred points of high elastic strain concentration and localized slip, when the applied strain is under but near the macroscopic elastic-plastic transition. We find that the very few localized slip bands are correlated with the development of only the highest elastic strain concentrations. Strain localization is specifically favored in crystals that have an outstandingly compliant orientation relative to all its neighbors and a non-equiaxed shape with sharp corners. These results explain that the presence of annealing twins in the microstructure significantly increases the probability of localization.

Presentation Title: Getting Stuck and Breaking Free: Adhesion, Friction, Strength and Toughness
Abstract: Many phenomena of scientific and technological interest are described by the evolution of free boundaries or free discontinuities. Examples include the peel front while peeling an adhesive tape, the rupture front of earthquakes, dislocations in solids and the crack set during fracture. This evolution takes place in a heterogeneous medium where the length-scale of the heterogeneities are much smaller than the length scale of interest. In such situations, it is natural to seek the overall or effective behavior at the scale of interest. This effective behavior is not characterized by averaging, but instead dominated by critical events. Thus, the effective behavior can be qualitatively different from the local behavior. This makes such problems difficult to study, but also offers opportunities for exploiting heterogeneities to dramatically material properties. This talk will discuss the underlying issues with examples drawn from fracture, friction, dislocation dynamics, phase boundary propagation and peeling of adhesive tape.

Presentation Title: Full-Field Methods for Characterizing the Non-Linear Anisotropic Response of the Anterior Cruciate Ligament of the Knee
Abstract: The Anterior cruciate ligament, or ACL, of the knee is a soft tissue structure comprised of two main bundles of hierarchical collagenous structures. As with all soft tissue, the ACL is extremely difficult to mechanically test, and determining its non-linear, anisotropic mechanical response has remained elusive. Yet, obtaining the mechanical properties of the ACL is exceedingly clinically relevant to the design of better replacement grafts for torn ACLs or to prevent ACL tears in the first place. This talk will focus on our recent efforts to characterize the ACL response utilizing full-field displacement measurement techniques that offer more accurate, repeatable, and comprehensive experimental data than traditional testing methods. We've pioneered full-volume characterization techniques that provide much needed insight into the inaccuracies associated with many current experimental protocols and also the shortcomings of some popular constitutive models in capturing the full 3D response of the ACL. I will describe how we use these data to develop an ACL constitutive model for implementation into computational models of the knee during regular gait and under impact loading simulations. Accurate computational models of the knee such as ours may one day be used to guide clinical practice to intervene to prevent an ACL injury or to determine the best course of action to repair an injury.

Presentation Title: Drag Reduction of Watercraft: Microfluidics Applied to Macroscale Objects
Abstract: When an object (e.g., boat) moves in a liquid (e.g., water), drag impedes its motion, consuming energy and limiting speed. Since maritime transportation alone accounts for a significant portion of the global oil consumption and greenhouse gas generation, a reduction of the water drag by even a small fraction would have a considerable benefit worldwide. Because the skin friction drag is the largest portion of the total drag experienced by most water vehicles, numerous mechanisms to reduce the skin friction have been explored for decades. However, none has been widely accepted because of poor energy efficiency. About a decade ago, superhydrophobic (SHPo) surfaces started to receive significant attention because the air layer between water and the surface can lubricate the water flows, decreasing the skin friction. Unlike other existing gas-lubricating methods, SHPo surfaces would hold a gas layer (called plastron) within the microscopic structures on the surface, making it possible to reduce skin friction without consuming energy to provide the gas. Despite two decades of research, however, drag reduction with SHPo surfaces has not been obtained for the most coveted application example, i.e., high Reynolds number flows in open water. This talk will present our recent achievement, i.e., the first successful large drag reductions (~30%, up to ~40%) with SHPo surfaces using credit-card-size samples tested under a boat on the sea at Reynolds number as high as 1.14x107 (friction Reynolds number as high as 5800). The results attest the importance of microscopic nuances of SHPo surfaces for a given application even if it is of macroscale, suggesting directions for other future goals as well.

Presentation Title: System Resilience: Definitions, Quantification and Associated Economics
Abstract: The concept of resilience is applicable to systems with anticipated performances and subject to disturbances. Understanding and quantifying resilience enable societies to use resources efficiently for enhancing or maintaining the performance of systems such as infrastructure. For example, natural disasters as disturbances resulted in worldwide direct damages of US$366 billion and 29,782 fatalities in 2011 alone. Storms and floods accounted for up to 70% of the 302 natural disasters worldwide, with earthquakes producing the greatest number of fatalities. Managing these risks and others rationally requires an appropriate definition of resilience and associated metrics. This presentation provides a resilience definition that meets a set of requirements with clear relationships to reliability and risk as key relevant metrics. Such metrics provide a sound basis for the development of effective decision- and policy-making methods for multihazard environments for various system types including lifeline, environmental, financial, etc. systems. The presentation also examines recovery, with its classifications based on level, spatial, and temporal considerations. The economics of resilience is briefly discussed.

Presentation Title: Design for Additive Manufacturing: Opportunities and Challenges
Abstract: Broadly speaking, the idea of design for additive manufacturing (DFAM) is to explore new design spaces to take advantage of the unique capabilities of AM processes. With tremendous design freedom available, resulting device designs can be complex geometrically, with complex material and property distributions, that perform multiple functions. At the same time, AM processes perform millions of operations to fabricate a part. Is it any wonder that parts exhibit more variability than in conventional manufacturing processes? In this talk, I explore the opportunities and challenges surrounding these issues of DFAM. Regarding opportunities, I highlight two directions. First, I present the idea of simultaneous design of a part, its material, and its manufacturing process since these are intimately linked in additive manufacturing. The fundamental need is to integrate materials information, specifically process-structure-property relationships, in order to determine if desired spatial distributions of properties are feasible given a material and a manufacturing process. Second, I highlight the need for methods of robust and reliability design to address process variabilities and enable part qualification. Regarding challenges, several topics are addressed, starting with the rapid changes in the AM industry. Additionally, a core attribute of AM processes is that both the part geometry and part material is fabricated simultaneously, in contrast to conventional manufacturing processes, which is the source of many challenges. The talk concludes with an overview of commercial software offerings to support DFAM, as well as standardization efforts that offer guidance to designers.

Track 18: Conference Wide Symposium
Name: Kai Goebel, System Sciences Lab at Palo Alto Research Center (PARC)
Presentation Title: Failure is not an ‘Option: Avoiding operational disruptions with mechanistic and data-driven damage prognostics- Sponsored by the NDPD Division’
Abstract: We are in an age where pervasive sensing, high communication bandwidth, and advances in AI have arrived at industrial equipment. The question is how one can leverage these advances for operational gain. To uphold operational functionality, these techniques flow into a Condition-Based Maintenance (CBM) strategy where maintenance is only performed on evidence of need identified through direct or indirect monitoring. Knowledge of an asset’s condition and how it will evolve is required such that the remedial action can be prescribed with sufficient lead time to minimize the cost and operational impact of the occurrence of a potential disruption. This strategy differs from “on-condition” maintenance in that an understanding of how much time is available before the asset loses functionality can be leveraged. The basic concept entails collecting and assessing data from NDE inspections and in-situ sensors to estimate remaining life of the system in question. This is done using either mechanistic, physics-based models or, as suitable, data-driven AI techniques. This talk lays out a roadmap of the tools and methods that are to be used to realize the promise of making failure not an option.
