Influence of fuel jet nozzle geometry on mixing enhancement in supersonic crossflow

Abstract

Hot-wire anemometer is used for turbulence measurements in the incompressible flow. To apply to the compressible flow, hot-wire anemometer was calibrated in jet of the compressible flow. Using it, Influence of geometry on mixing effect of gas injecting supersonic flow was clarified. TypeB Tips promoted mixture at x=10mm, y=10mm and x=30mm, y=15mm. TypeA and TypeB Crest showed similar mixing characteristic.
