Unsteady Flow Phenomena in Turbomachines

Abstract : This report describes work carried out at the Gas Turbine Laboratory at M.I.T. as part of our multi-investigator effort on basic unsteady flow phenomena. Within the overall project, four separate tasks are specified. These are, in brief: I. Unsteady Flow in Compressors; II. Computational Techniques for Unsteady Flows; III. Unsteady Phenomena, Inlet Distortion, and Flow Instabilities in Multistage Compressors; IV. Unsteady Vortical Wakes Behind Blade Rows - Prediction of Relationships with Blade Properties. Computational fluid mechanics; Unsteady flows in turbomachines; Vortex wakes; Compressor stability; Transonic compressors.
