The problem of obtaining proper flow spreading together13; with useful pressure recovery across rapidly expanding13; diffusers is of considerable practical importance, Many13; different approaches to this end have, been reported in13; literature, e.g. vortex generators, screens or bailies, surface roughness, corrugations, etc., apart from the use of direct boundary-layer control. These methods have the common13; aim of preventing separation from the walls of the diffuser. 13; With increasing expansion angle and area-ratio, however, the effectiveness of these methods either breaks down or is obtained at a high cost of pressure recovery.
