Fluid Dynamics of High Performance Turbomachines.
Abstract
This report describes work which is part of a study on high performance turbomachinery fluid dynamics. Within the general topic, four separate tasks studies include: 1) Loss mechanisms and loss migration in transonic compressors, including development of advanced instrumentation for measurements of wake radial transport and analysis of unsteady vortical wake structures. 2) Experimental and theoretical study of flows in casing and hub treatment, including mechanisms for stability enhancement in compressors and unsteady fluid dynamic interactions between passage and groove flows. 3) Computational techniques for turbomachinery, including inverse (design) calculation procedures for transonic turbomachine blades accounting for viscid/inviscid interaction. and 4) Theoretical modelling of stability and unsteadiness in transonic compressor flow fields, including analyses of unsteady temperature fluctuations due to vortex shedding. Keywords: Transonic compressors; Compressor stability; Casing treatment design; Vortex wakes; Unsteady flow in turbomachines.
