Measurement of Velocity Distributions in Turbulent Jets Using a Laser Doppler Velocimeter.

Abstract

The theory of operation of Laser Doppler Velocimeters if discussed for both reference beam and differential Doppler modes. Current entrainment models for velocity distributions in vertical axisymmetric turbulent buoyant jets in a quiescent ambient are reviewed. A specific Laser Doppler Velocimeter is used to measure the velocity distribution found in a vertical, axisymmetric turbulent jet discharge into a quiescent ambient and the results are compared to theory.
