The application of laser scattering to flow field diagnostics
Abstract
The laser Raman scattering and Doppler velocimetry were combined to determine thermodynamic and fluid flow variables used in experimental fluid mechanics. Concentration and temperatures of nonionized and ionized species were measured; velocity, turbulence intensity, and cross-correlation parameters can be obtained in hostile environments simultaneously and nonintrusively. The spontaneous Raman effect can provide information on the concentration and temperature of ionized species in a plasma which can be applied for the characterization of MHD flows; the spontaneous and coherent anti-Stokes Raman scattering techniques may generally complement each other.
