Laser Velocimeter Measurements in Turbulent and Mixing Flows. Part III.

Abstract

Experimental and analytical studies of subsonic flow over a backward facing 2-D step and in a cylindrical simulated dump combustor were conducted. A laser velocimeter was used to obtain mean velocities and turbulence quantities. A method for detecting and eliminating velocity bias errors in such measurements was developed. The 2/E/FIX computer code used for numerical modeling predicted the mean velocity field satisfactorily, but was less effective in computing turbulence quantities. (Author)
