Radial Mixing in Turbomachines.

Abstract

The main tools for the prediction of convective radial mixing are developed. The secondary flows needed for the convective mixing are found from pitch averaged vorticity equations combined with integral methods for the computation of 3d end-wall boundary layers, 3d profile boundary layers and 3d asymmetric wakes. This integral approach requires less approximations than previous radial mixing theories and only three empirical constants are required. The convective mixing coefficient of Adkins and Smith is found from the resulting secondary flow velocities. The method is applied to some standard test cases, where secondary flow patterns are compared with available test data.
