    Transverse Structure in Turbulent Flow Using the Relief Technique

    The investigation of the transverse structure of the velocity field in turbulent flow is of great interest because, while the incompressibility relation severely constrains the possible longitudinal structures...

    Filtered Rayleigh and Relief Imaging of Velocity, Temperature, and Density in Hypersonic Flows for the Study of Boundary Layers, Shock Structures, Mixing Phenomena, and the Acquisition of in-Flight Air Data

    We describe here several new techniques which have potential for quantitative diagnostics in hypersonic flow fields. In particular, RELIEF flow tagging of oxygen and Rayleigh scattering are examined. Both have...

    Two-dimensional measurement of density, velocity, and temperature in turbulent high-speed air flows by UV rayleigh scattering

    Instantaneous cross-sectional images of turbulent air flows with densities on the order of one atmosphere or less can be obtained in a straightforward manner using far ultraviolet Rayleigh scattering. These im...
