PIV Measurements of Air Flow in a Swirl Type Combustor

Abstract

This study deals with aerodynamics phenomena in a swirl type combustor that has two swirlers. The Particle Image Velocimetry (PIV) technique has been used to get the velocity filed of swirling flow without combustion. It is revealed that high turbulence area occurs at a boundary of recirculation region at downstream of swirler and an interaction region of two swirling flows.
