Exhibitor Theater

Every visitor, delegate and exhibitor at the EXPO can attend any of the following presentations, FREE OF CHARGE. Each is delivered by one of the Exhibitors at the EXPO - all of them leading experts in their field.

 

Laser-based powder bed fusion (PBF-LB/M) of high γ’ alloys such as CM247LC offers the potential to produce high-performance turbine blades with complex internal structures. While these hard to weld materials are typically not processable by PBF-LB/M due to their sensitivity to cracking, recent advances in process strategies enable nearly crack-free manufacturing of CM247LC with columnar, coarse-grained (DS-like) microstructures, as well as equiaxed structures with finer grains. This presentation highlights the resulting material properties including stress-rupture and high temperature tensile performance and provides insights into additive manufacturing of turbomachinery components made from CM247LC, from building process to heat treatment. CM247LC for turbomachinery applications with advanced PBF-LB/M strategies presented by Tobias Novotny, EOS Metal Process Engineer from EOS.

Introduction to Seals for Turbomachinery - This presentation provides an overview of seals used in turbomachinery, covering their fundamental principles, design considerations, and performance impacts. Topics include labyrinth, honeycomb, hole pattern, windback, and thermoplastic seals, with a focus on their roles in efficiency, reliability, and leakage control. Attendees will gain insight into seal selection, common challenges, and advancements in sealing technology for high-speed rotating equipment. Presented by Andy Alcantar from Miba Industrial Bearings.

Turbomachinery design requires accurate understanding of physics behavior of the machinery being designed. Accurate simulation of physics behavior requires high fidelity meshes that are aligned to capture the physics accurately. Developing high fidelity meshes for turbomachinery is often a choice between automation and confidence in the solution accuracy. The new GridPro Xpress series from PDC bridges the chasm between automation and solution accuracy. With the GridPro Xpress series, we get full automation of exceptionally high quality multiblock meshing various turbomachinery components like blade rows and volutes allowing for efficient Turbomachinery design with confidence.

For turbomachinery design optimization, automation with reliable accuracy is a fundamental requirement. The combination of GridPro Xpress with automated design systems such as CAESES transforms the turbomachinery design process to significantly better designs in less time.

This presentation will explore how GridPro Xpress can accelerate your turbomachinery design with intelligent structured meshing. Presented by Peter R. Eiseman of GridPro.

Presented by Giacomo Saletti from NOVA.

HVTS™ Cladding in Advanced Gas Turbines: Field Performance and Applications Beyond the Hot Gas Path presented by Eric Duvekot from Integrated Global Services (IGS).  Since 2022, Integrated Global Services (IGS) has applied its proprietary HVTS™ cladding on more than a dozen advanced-frame gas turbines to combat high-temperature oxidation and spalling. This presentation examines common damage mechanisms, highlights inspection-verified performance after thousands of operating hours, defines typical protection zones, and explores additional combined cycle components where users are applying HVTS to permanently eliminate metal wastage.

 

Maintaining and validating a digital twin for turbomachinery applications is key to derive reliable lifetime and performance predictions. Usually, engineers and analysts use test data and validated models from prior programs to calibrate and enhance their digital twins. However, the calibration and validation procedures, often referred to as “data matching” in the thermal community, are generally manual and can take several months due to the number of parameters to adjust, the number of sensors used, and the multiple operating conditions to consider. This presentation highlights how using an adjoint-based solver can help reduce development cycles, even when working with hundreds of parameters simultaneously in complex turbomachinery thermal models. Presented by Hussein Daou, Product Owner, Thermal-Flow & Multiphysics Product Management from Maya HTT.

This presentation addresses the development and the manufacture of a gas turbine Resonator Ring, using a wire-directed energy deposition (DED) process - wire arc additive manufacturing (WAAM) presented by Tad Steinberg from Siemens Energy.

Simulation- and Data-Driven Design of Turbomachinery: Many different competing requirements, such as aerodynamic, structural, and manufacturing aspects, play a role in the design of a turbomachinery component and often need time-consuming iterations to properly balance. This presentation will focus on using smart parameterized geometry models that consider all necessary requirements and an integrated design process, allowing for a rapid exploration of the feasible design space and optimization. Presented by Mattia Brenner from Friendship Systems, Inc.

Peregrine Turbo Technologies and TURBOCAM International will present an overview of their collaborative efforts to bring to market a highly efficient, cost effective sCO2 geothermal engine for the power generation market presented by Tim Noronha & Eric Vollnogle.
