The present work relates to the analysis of flow through the parallel hub and diverging casing annular diffuser. In this analysis development of flow, flow reversals and separation of flow have been visualized through the diffuser walls with and without swirl. The casing angle and area ratio have been taken as 60 and 2.5 .The swirl angle was varied from 00to 250 at the inlet of diffuser. The analysis was carried out for flow regimes with various experimentally obtained inlet velocity profiles with or without swirl [1]. Longitudinal velocity, swirl velocity have been calculated along the different diffuser passage heights at different traverses along the length of annular diffuser. In the present work CFD approach was used to find the results by using turbulence model.
