Abstract
In order to investigate the structure of Mach 8 flowfields and the mixing of wall injected fuels, two different diagnostic imaging techniques have been developed. The first uses carbon dioxide enhanced Filtered Rayleigh Scattering (FRS) for imaging the freestream flow and the boundary layer. The second technique uses laser induced fluorescence of sodium seeded into helium as a fuel simulant to provide information on injection and mixing in hypersonic flows. This paper will discuss the development of these diagnostics and their transition into the Mach 8 test facility at the Princeton Gas Dynamics Laboratory.
