Abstract
The present work reports a computational study of flow through axial swirler for various swirl angles from 200 to 700 in steps of 100. Three dimensional flow through the axial swirler have been simulated by means of computational fluid dynamics (CFD) using the code Ansys – Fluent 13. The objective of this work is to understand the flow field characteristics downstream of the swirler at different axial locations and to find length and width of Central Toroidal Recirculation Zone (CTRZ) for all six cases of swirler. The recirculation velocities at the centre and corner regions are well captured by solving the appropriate governing equations, namely, conservation of mass and momentum using the SIMPLE algorithm. Turbulence has been modelled using Reynolds Stress Model. The numerical predication of mass flow rate has been compared with experimental correlation. It has been observed that, good agreement is obtained between numerical predication and the experimental correlation
