Abstract:

The proven laser-induced fluorescence LIF technique to measure the particle temperature, and the proven filtered Rayleigh scattering method to measure the gas density will be used simultaneously with the CompLDV for low uncertainty information on supersonic turbulent test flows. The accurate calculation of supersonic turbulent flow behavior for Air Force applications is still needed. It is clear from literature reviews that experimental research is needed on the structure of supersonic shockboundary layer interaction SBLI over the rough wall surface using advanced experimental methods that can provide the needed turbulence structural information to develop computational models.
