Title

STUDY AND ANALYSIS OF PARALLEL HUB AND DIVERGING CASING AXIAL ANNULAR DIFFUSER WITH AREA RATIOS OF 4

Abstract

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 with and without swirl. The equivalent cone angle and area ratio have been taken as 200 and 4.The swirl angle has been 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.Longitudinal velocity and swirl velocity profiles have been checked along the different diffuser passage heights x0.1, x0.2, x0.4, x0.6, x0.8 and x0.9 at different traverses along the length. In this present work CFD approach has been used to find the results by using RNG k-ε turbulence model. The results obtained from CFD have been compared with experimental results. Finally parametric investigations have been carried out by varying swirl angle.. Keywords:-Annular diffuser, Pressure recovery coefficient, Swirl velocity, Area ratio, Equivalent cone angle and CFD.

Key Words

Annular diffuser, Pressure recovery coefficient, Swirl velocity, Area ratio, Equivalent cone angle and CFD.
