Turbulent Boundary Layers on Centrifugal Compressor Blades: Prediction of the Effects of Surface Curvature and Rotation

Abstract

A method for calculation of turbulent boundary layers on curved, rotating surfaces is presented, and the applicability of the method to the prediction of attached flow over compressor rotor blades is indicated. Calculated results are compared to existing data sets. Additional sample calculations to study the effects of rotation are also presented. Correlations of these calculated results provide a simple method for estimation of the effects of rotation on skin friction, cf, and boundary-layer shape factor, H.
