Jets in Crossflow — Effects of Heat Release

  • Chapter
Manipulation and Control of Jets in Crossflow

Part of the book series: International Centre for Mechanical Sciences ((CISM,volume 439))

Abstract

Detailed measurements of the velocity field in the symmetry plane of two jets and two jet flames in crossflow are obtained using Particle Image Velocimetry. The jets issue into a wind tunnel at density-weighted jet-to-cross flow velocity ratios r = 10 and r = 21, with corresponding Reynolds numbers 6,000 and 12,800. The changes in the flow due to the effects of heat release are examined and ensemble statistics of the velocity field are derived from these datasets. Simultaneous Planar Laser-Induced Fluorescence imaging of the OH radical is performed in selected regions of the flames. Results suggests that flame/flow interaction is strong near the lifted flame base, but increasingly weaker further downstream.
