Annulus Wall Boundary Layers in Turbomachines.
Abstract
The paper reviews a substantial body of fundamental and applied research work on the subject of annulus wall boundary layers in turbomachines. A product of this work is a method for predicting, with reasonable accuracy, the full three-dimensional boundary layer that develops through a single blade row. The limitations of the method are discussed in relation to the experimental information available to the authors. In Part 2 the fundamental work is subjected to scrutiny in order to extract a boundary layer calculation method suitable for estimating the effects of annulus wall boundary layers on the performance of turbomachines. It is shown that a great many assumptions and simplifications are necessary at the present time but that reasonably satisfactory estimates are nevertheless possible. A computer program for the estimation of annulus blockage is listed.
