Turbulence Measurements in a Plane Free Jet at High Subsonic Velocities.
Abstract
This thesis reports the methods and results of an experimental study of the turbulence parameters for a plane jet at high subsonic velocities. Apparatus with a nozzle exit 1 x 10 cm was designed for two-dimensional flow with primary measurements across the width of the jet. Three measurement planes at 25, 50, and 75 jet widths downstream were chosen to provide conditions ranging from the turbulent mixing region to that where self-preservation nearly prevails. Similarily, three nozzle exit velocities at M=0.4, M-0.6, and M-0.8 were chosen to provide a range of flow conditions. Techniques employing hot wire anemometers with on-line electronic data analysis equipment are described.
