Abstract: The authors’ preceding analysis on centrifugal vaneless diffusers is used to examine the influences of diffuser geometries and of flow inlet conditions on the critical flow angle for reverse ...

Abstract: There is controversy about the mechanism of decay of the asymmetric flow in the vaneless diffuser of centrifugal blowers. In order to clearly observe the behavior of asymmetric flow, every ...

Abstract: An experimental study of the influence of tip clearance on the stall limits of compressor blades was conducted on a rectilinear cascade. By using the mirror and image technique the end wall ...

Abstract: In this report a method of analyzing subsonic inviscid flow between blades on a stream surface of revolution of a turbomachine, which may be an axial, a radial, or a mixed-flow type, is ...

Abstract: In this report, a method of analyzing steady, three-dimensional, subsonic, nonviscous flow through a turbomachine with arbitrary hub and shroud shapes and with a finite number of blades is ...

Abstract: Experimental investigations have shown that the flow discharged from a centrifugal compressor or pump impeller into a diffuser is often unsteady and axially asymmetric. A theory based upon a ...

Abstract: An analytical method is proposed to evaluate the flow behavior in vaneless diffusers assuming that the flow is not symmetric between the walls. In the analysis momentum integral equations are ...
