Modeling Methods for Particle Flow and Heat Transfer for Concentrated Solar Power Applications
Workshop Description:
This workshop will focus on a series of short tutorials/presentations that discuss modeling flow physics and heat transfer (conduction, convection, radiation) in particle flow systems with applications to Gen3 CSP technologies.
Workshop Agenda:
Intro to workshop
Presented by: Rohini Bala Chandran, Assistant Professor, University of Michigan
Biography: Prof. Bala Chandran is an Assistant professor at the University of Michigan and has been active in the space of developing continuum heat and mass transfer, and radiative transport models for solar thermal receiver and reactor applications for over 15 years now. Her research group is developing pioneering multimode heat transfer modeling tools using discrete element methods and fascinated by the rapid development and adoption of different discrete element modeling tools and platforms to predict flow and heat-transfer behavior in particle systems, especially in the CSP-space over the last decade.
DEM Modeling: Introduction + Tutorial
Presented by: Christoph Goniva, DCS Computing
Biography: Dr. Christoph Goniva received his Ph.D. in Computational Fluid Dynamics in 2011, at the Johannes Kepler University (JKU) in Linz, Austria. From 2011 to 2014, he has been Senior Research Associate at the Department of Particulate Flow Modelling at JKU, where he headed a DEM and CFD-DEM modelling team together with Dr. Christoph Kloss. Dr. Christoph Goniva is co-founder and director of DCS Computing, the producer of the DEM software Aspherix® and the CFD-DEM software CFDEM®coupling.
Radiation & Heat-transfer Modeling in Particle Flow Systems
Topic: Reduced-order view factor models and parelllizing radiative flux calculations for DEM simulations
Presented by: Bingjia Li & Zijie Chen, 4th year Ph.D. Candidates, University of Michigan<
Biography: Bingjia and Zijie are fourth-year Ph.D. candidates at the University of Michigan. They are working on radiative heat transfer modeling for granular flow.
Topic: GUI-enabled radiative modeling suite for particle-based simulations including accelerated MCRT, distribution factor surrogate-models, and volumetric participating media.
Presented by: Andrew Schrader, Assistant Professor, Dayton University
Biography: Dr. Andrew J. Schrader received his Ph.D. in Mechanical Engineering from Georgia Tech in 2019. He is presently the director of the Dayton Thermal Applications (DaTA) laboratory and Assistant Professor at the University of Dayton. The DaTA Lab has been investigating harnessing of concentrated solar-thermal resources to produce process heat for sCO2 power cycles, thermochemical systems, desalination, and materials production. Additionally, the DaTA Lab works closesly with AFRL on the thermal management of high-speed vehicles. Dr. Schrader has long been fascinated with promoting access to modeling tools and methods to the CSP community.
Topic: Systematic calibration of contact model parameters, adding a new heat transfer model to LIGGGHTS, verification and validation of heat transfer models
Presented by: Johannes Grobbel, Group leader Process Control and Modeling, Institute of Future Fuels, German Aerospace Center (DLR)
Biography: As one of the first researchers who modeled solar particle receivers with the DEM, Dr. Johannes Grobbel calibrated contact model parameters and developed heat transfer models in his Ph.D. thesis, which he defended in 2019. Now as a group leader at the DLR Institute of Future Fuels in Jülich, Germany, he investigates solar driven thermochemical redox cycles for hydrogen and synthetic fuel production, in particular processes where particles are involved.
CFD-DEM modeling for multiphase gas-solid flows
Topic: p-f-p conduction parameters in DEM
Presented by: Krutika Appaswamy, Ph.D. Candidate, Purdue University
