Laser Doppler Velocimeter Measurements in a Turbulent Jet Exiting into a Cross Flow

Abstract

Measurements were made of horizontal and vertical velocity components along the center line plane of a turbulent jet exiting into a cross flow. The dual scatter laser Doppler velocimeter was used in both the continuous wave mode and the individual realization mode. In the latter case, numerical averaging over many individual measurements was used to compute the average velocity components. Encouraging results were obtained which indicate that the laser Doppler velocimeter will become an important tool in the field of experimental fluid mechanics.
