A Study of the Turbulent Structure of a Two-Dimensional Diffusion Flame formed Behind a Slender Bluff-Body

摘要

An experimental investigation of confined turbulent reacting wake flows past a 2D square cylinder with planar fuel-jet injection into the vortex formation region is presented. Measurements of mean and turbulent velocities and temperatures and a sample of results on related statistics, obtained with laser velocimetry an thin digitally compensated thermocouples throughout the wake region for two Reynolds numbers an for a range of fuel-to-air velocity ratios (FAVR), are discussed.
