Combined LDV (Laser Doppler Velocimetry) and Rayleigh Measurements in a Complex Turbulent Mixing Flow
Abstract
The cold flow behind a backward facing step with injection of a foreign bleed gas was investigated using a simultaneous laser Doppler velocimetry-Rayleigh scattering technique. The facility simulates the flow field in the flame stabilization region in a solid fueled ramjet. Velocities and bleed gas concentrations and the resulting mixing pattern were measured. Particular attention was paid to the covariance of the velocity and bleed gas concentration which is a measure of the turbulent mass transport in the flow field. A novel reduction technique was utilized in the reported measurements.
