ASME IGTI Committees

The heart of the ASME International Gas Turbine Institute is its highly successful committee structure. ASME IGTI's Committees provide regular ongoing forums for program development and technical exchange, addressing all areas of technical expertise related to gas turbines, turbomachinery and related equipment.

The Committees organize the high quality paper and panel sessions for the annual conferences sponsored by ASME IGTI. Committee members consist of leading engineers in close contact with the latest developments in turbomachinery equipment, improvements in techniques, and introductions of new practices. They bring such developments to the annual ASME TURBO EXPO where these activities may be reported, discussed freely, and their benefits shared by the entire turbomachinery community.

Over 30 countries are represented by the Committee membership, derived from academic, government, and industrial affiliations.

All ASME IGTI Committees support their individual missions with the following activities:

  • Monitoring current issues and trends in gas turbines, turbomachinery, and related equipment, and organizing related sessions for the TURBO EXPO or other related programs. Committee members assist in this process by suggesting session topics, presenting papers, participating on panel discussions, and acting as Session Chair or Vice Chair.
  • Supporting the ASME IGTI Review process, which assures quality peer reviewed published paper presentations. Committee members assist in this by coordinating peer reviews according to the ASME IGTI guidelines, communicating needed revisions to the author, reviewing papers, and assisting the Journal editors.
  • Encouraging cooperation with other professional societies who share common interests. ASME has cooperative agreements with many engineering societies throughout the world. Although ASME membership is not required to join an ASME IGTI Committee, it is recommended. ASME membership is required to serve as Committee Chair or Vice Chair.
  • Actively working to expand the membership to maintain the breadth and depth of experience necessary to address the Committee's focused area of interest. The most valued benefit of being an active Committee member is the opportunity to interact with an international membership of leading professionals in the turbomachinery industry.
  • Recognizing technical accomplishments by nominating papers for ASME and Committee awards. Several highly-respected awards are presented annually at the ASME TURBO EXPO.

Nature of Transonic Compressor Flow and its Design Implications

A key problem in transonic compressor and fan design is that although a 3D description of the flow is necessary to correctly capture the shock, accounting for it during the sectional detailed design is difficult because the key driving design parameters are still poorly understood. In this webinar, it is shown that for inlet relative Mach numbers between 0.85 to 1.20, the pressure rise across the shock is purely a function of the 3D streamtube area at the throat at over the inlet area A1. This finding is based on three key transonic flow features, discussed in detail within this seminar, being present together across a wide range of more than 2000 representative transonic compressor and fan designs published online (

The second half of the webinar discusses the implications of this newfound clarity to practical transonic rotor design. First, it outlines the important preliminary geometric design parameters set prior to the detailed design phase and then describes a simple and efficient physics-based method for designing optimal transonic multistage compressor rotors.  The key to this novel method is that the spanwise variation of At /A1, is extracted directly from the 3D CFD. The spanwise distribution of the area ratio is then adjusted iteratively to 'aerodynamically balance' the shock structure across the blade span.

This simplified design process will be shown, through representative rotor redesign examples, to achieve highly satisfactory results whilst providing a physically intuitive way of understanding how the design was improved. Hence, it is of great practical utility and valuable learning for any compressor or fan designer.

Exploring Additive Manufacturing for Advancing Turbine Cooling, Dr. Karen A. Thole

Commercial aviation is responsible for between 2.0 and 2.5 percent of the total global COemissions of which 90 percent comes from large single-aisle and twin-aisle aircraft.  With the exception of fully electric, the majority of the future aviation propulsion systems will use a gas turbine as the power plant.  In response to the International Civil Aviation Organization’s pledge to support an aspirational net zero aviation goal by 2050, the pace at which gas turbines are developed must hasten. While increasing turbine efficiencies is key to reducing carbon emissions, this must be balanced with component life, which is set by operational temperatures.  Recent advances in the field of additive manufacturing (AM) have opened up possibilities to evaluate new features for cooling turbine airfoils with a much more rapid turnaround relative to conventional casting. The opportunity is to exploit the use of additive manufacturing in re-thinking cooling schemes for components while considering the inherent effects of the metal additive process.  This talk will also provide insights on various challenges associated with additively manufacturing components.

Dr. Karen A. Thole is a Distinguished Professor in the Department of Mechanical Engineering at The Pennsylvania State University.  Dr. Thole’s expertise is heat transfer, additive manufacturing, and instrumentation development.  She directs the Steady Thermal Aero Research (START) Lab where experimental and computational studies are conducted to advance aviation sustainability and power generation through highly efficient turbines.  She is a Fellow of ASME, AIAA and the Royal Aeronautical Society.  She has been a member of several National Academy of Engineering studies; has served on NASA advisory committees; and is a member of the Department of Air Force Scientific Advisory Board.  Her work has been recognized by ASME’s R.

Accelerating Turbomachinery Design: The Role of High-Fidelity Simulation and Machine Learning, by Richard Sandberg

To accelerate the deployment of cleaner energy and propulsion technologies, their development time and costs need to be considerably reduced. A key enabler for this is stronger reliance on computational fluid dynamics (CFD) for the design of turbomachinery components because CFD predictions with sufficient reliability can reduce the number of costly and time-consuming laboratory experiments and test campaigns. First-principles based simulations are most accurate and have the potential to elucidate mechanisms that can be exploited for further efficiency gains. Their excessive computational cost, however, preclude their use in a design context and therefore modelling is required. Unfortunately, the inaccuracies introduced by RANS- or URANS-based CFD modelling approaches can limit the impact CFD can have on technology development.

This presentation will present state-of-the-art high-fidelity simulations of bladed turbomachinery components, harnessing the power of the latest GPU-accelerated supercomputing systems. It will include discussion of cases with fully resolved realistic roughness and show how physical insight relevant to designers has been extracted. The talk will also introduce some of the inherent turbulence modelling errors and how those can be addressed with a novel machine-learning approach that can use both high-fidelity and sparse experimental data. It will be shown that closure models developed using the gene-expression programming approach, which are interpretable and easily implementable into CFD solvers, outperform traditional models both for the cases they were trained on and for cases not seen before.

Richard is Chair Professor of Computational Mechanics in the Department of Mechanical Engineering at the University of Melbourne. He also leads the Power Generation and Transport Program of the Melbourne Energy Institute.

His main interests are in (i) high-fidelity simulation of transitional and turbulent flows to gain physical understanding of flow and noise generation mechanisms, (ii) pursuing novel machine-learning approaches to help assess and improve low-order models (e.g. RANS) that can be employed in an industrial context.

He received his PhD in 2004 in Aerospace Engineering at the University of Arizona and prior to joining the University of Melbourne, he was a Professor of Fluid Dynamics and Aeroacoustics in the Aerodynamics and Flight Mechanics research group at the University of Southampton and headed the UK Turbulence Consortium ( He was awarded a veski innovation fellowship in July 2015 entitled: "Impacting Industry by enabling a step-change in simulation fidelity for flow and noise problems" and has been granted an Australian Research Council Future Fellowship for 2020-2024 to work on integrating high-fidelity simulation and machine-learning based turbulence modelling. He is an editor for Flow, Turbulence and Combustion and the Journal of Turbomachinery and is part of the ASME Gas Turbine Technology Group.
