Abstract:

This report describes work carried out at the Gas Turbine Laboratory at MIT during the period 102089 - 101992, as part of our multi-investigator effort on basic unsteady flow phenomena in turbomachines. Within the overall project four separate tasks are specified. These are. in brief 1 The Influence of Inlet Temperature Nonuniformities on Turbine Heat Transfer and Dynamics 2 Assessment of Unsteady Losses in Stator Rotor Interactions 3 Unsteady Phenomena and Flowfield instabilities in Multistage Axial Compressors IV. Vortex Wake-Compressor Blade Interaction in Cascades A New Rapid Method for Unsteady Separation and Vorticity Flux Calculations.
