Gas thermodynamics and optics of a monodisperse supersonic jet interacting with an aerodynamic body

On the basis of the previously developed gas dynamics model of the polydisperse jet flowing over a blunt body, the optics of a compressed layer is studied under close-to-experimental conditions. The effect of scattering of monochromatic radiation by the particles on the observed picture in the “laser sheet” plane is numerically estimated. The study is carried out on the assumption that the cloud formed by the particles is optically thin (single scattering). The effects of absorption and scattering of the radiation by the carrying gas are neglected. The numerical studies have been carried out for wide ranges of the particle sizes and optical parameters of the matter.
