Development and Application of Oxygen Flow Tagging for Velocity Measurements and Flow Visualization in Turbulent Three-Dimensional Supersonic Flows
Abstract
Flow tagging by Raman Excitation plus Laser-Induced Electronic Fluorescence (RELIEF) and ultraviolet Rayleigh scattering have been developed to measure instantaneous velocity profiles, temperatures, and density cross sections in air. Experiments have been undertaken in supersonic free jets and supersonic boundary layers. In these experiments lines have been written into air to give the first direct images of velocity structure in supersonic free shear layers, and UV Rayleigh scattering has been used to achieve the first measurements of instantaneous two-dimensional density cross sections in free jets and in supersonic boundary layers. Keywords: Supersonic flow; Turbulence; Flow visualization; Three-dimensional compressible turbulent flow.
