An Analysis of Experimental Data on Air Ionization in a Compressed Layer near the Surface of a Spherically Blunted Cone at a Velocity about 5 km/s

Using a two-dimensional model of physicochemical gas dynamics and the author's computer code NERAT-2D, an analysis of experimental data on air ionization in a compressed layer near the surface of a spherically blunted cone at a velocity of 5.34 km/s at a height of 82–48 km was performed. Within...

Description
Summary:Using a two-dimensional model of physicochemical gas dynamics and the author's computer code NERAT-2D, an analysis of experimental data on air ionization in a compressed layer near the surface of a spherically blunted cone at a velocity of 5.34 km/s at a height of 82–48 km was performed. Within the framework of the system of equations of motion of a viscous compressible and heat-conducting gas, nonequilibrium physical and chemical processes in a compressed layer are taken into account. A comparison with experimental data on the level of electron concentrations in the compressed layer is given. Calculations of the distribution of densities of convective heat fluxes for the experimental conditions are performed.
