ASME United Kingdom Section: Industrial Challenges in Large Thermally Enabled Structural Whole Engine Modelling

Description

Join the ASME UK Section for a virtual presentation with Dr. Akin Keskin. Understanding gas turbine design at a system level presents a difficult challenge. Accurate predictions of gas turbine behaviour before whole engine tests are completed are invaluable in preventing costly design changes in the latter stages of the design life cycle. The talk will present a new approach to create very a high fidelity whole engine models - specifically, thermally enabled structural models - to predict component displacements up to system level interactions across the whole engine. The talk include a discussion about the challenges and analysis methodologies used to thermally solve the whole engine cycle, the mapping procedure to translate thermal data to a structural model, and the approach taken to solve very large simulation models explicitly at a chosen condition to a pseudo-steady state. Finally, a comparison to existing test data will be shown to validate the simulation results and recommendations made how physical testing can be supported in the future using the presented methodology. Dr. Akin Keskin holds a degree in Aerospace Engineering from the Technical University of Berlin in Germany and a PhD in Mechanical Engineering from the Cottbus University in Germany. He lectured Compressor Aerodynamics and High-Speed Aerodynamics in Berlin and Cottbus.
