Secondary Flows in Turbomachines

Abstract

These proceedings contain the 24 papers presented at the meeting on secondary flows in turbomachines. The meeting was arranged in the following sessions: Basic flow phenomena (6); Experimental results (5); Three-dimensional computation and comparison with experiments (5); Tip clearance flows (4); and Secondary flow effects on heat transfer (4). The specialists' meeting offered a forum for experts to discuss computational and experimental methods and results for secondary flow in cascades, compressors and turbines. CFD was found to be an adequate tool to represent qualitative phenomena, but on the accuracy of predicting losses and exit angles there was some disagreement. Many papers dealt with experimental investigations which are obviously essential for evaluating secondary flow models. Keywords: Three dimensional flow computations; Cascade structures; Axial flow compressors; Airfoils; Turbulent flow/mixing; Nozzle guide vanes; Transonic nozzles; Aspect ratio; Centrifugal impellers; Radial compressors; Blade tips; Turbine blades; Cascades fluid dynamics; Compressors; End wall flow; Computational fluid dynamics; Tip leakage flow; Secondary flow; Turbine guide vanes.
