S0506-2-1 Application of a High-Order LES Model to investigate Redistribution of the Inlet Temperature Distortion in a Turbine
詳細
Numerical studies of 3-D incompressible viscous unsteady flow within an axial turbine stage are analyzed in this work. The flow exiting the combustor and entering the turbine of a gas turbine engine is known to contain both spatial and temporal variation in total temperature. Experimental results indicated that hotter fluid migrates toward the pressure surface and cooler fluid migrates towards the suction surface. The main purpose of this study is to test the performance of a high-order LES model in terms of predicting this type of highly complicated unsteady flow and heat transfer phenomena
