Abstract

The effect of a coaxial jet on the film-cooling performance downstream of a suddenly expanded swirling flow in a film-cooled pipe is studied. A flat-vane swirler situated upstream before expansion is used to produce the swirling flow. Both the radial temperature distributions and the film-cooling effectiveness are measured, and the results are presented and discussed. In the experiment, the jet/mainstream velocity ratio ranged from 0-1.5, the swirl number from 0-0.6, and the blowing parameter from 0.5-2.0.
