Abstract

A 2D PIV technique was applied to investigate the swirling flow motion inside a rectangular-shaped model chamber. Flow velocity profiles are analyzed through several planes at the center and off-axis of the swirler over three cross-sectional views of x-y, y-z, and x-z. A comparison of axial and radial velocity profiles is given over these planes to ascertain the effect of rectangular confinement inside the combustor. Flow kinetic energy near the walls is investigated to study the highly disturbed regions and areas of flow impingement. A vorticity and vector analysis is presented on the x-z plane where the flow development was found to be under the effect of a CCW and CW swirler alongside the imbalanced condiment ratio.
