Development and Application of Oxygen Flow Tagging for Velocity Measurements and Flow Visualization in Turbulent Three-Dimensional Supersonic Flows
Abstract
Demonstration is presented of the oxygen flow tagging under conditions which duplicate the Mach 3 facility. These tests were done in an underexpanded axisymmetric jet up to Mach 4. Velocity data was taken through the core and across the free shear layer of this jet and images were generated of instantaneous flow structure from which are computed the average velocity profiles, turbulence intensity, and the axial velocity correlations. Simultaneous two-line flow tagging was done that data was used to generate stream-wise velocity correlations in the same axisymmetric jet. The data which has been generated has been compared with a high-speed subsonic jet to give us a quantitative measure of the difference between supersonic and subsonic turbulence. Keywords: Flow diagnostics, Velocity measurements, Temperature measurements, Density measurements, Laser diagnostics, Supersonic flows.
