INFLUENCE OF COMBUSTOR UNSTEADINESS ON THE AEROTHERMAL LOAD OF A HIGH-PRESSURE TURBINE STAGE USING SCALE-RESOLVING CFD SIMULATIONS

Abstract Aerothermal interaction between the combustor and the high-pressure turbine is critical for engine efficiency. Standard steady-state methods fail to capture the highly unsteady flow features at the combustor-turbine interface, leading to uncertainties in thermal load pre...
