On the asymptotic theory of the three-dimensional flow of a hypersonic stream of radiating gas around a body

Abstract

The three-dimensional flow of a hyersonic stream of ideal gas round bodies of arbitrary thickness allowing for radiation at high temperatures is investigated using the method of a thin optically transparent shock layer, which is a generalization of the well-known method of a thin shock (boundary) layer /1/. Using the fundamental property of the gas in the thin shock layer, which expresses the conservation of the ratio of the stream component of vorticity along streamlines to the density of the gas /2,3/, an analytic solution is obtained of the non-linear problem of the flow round a body bounded by a surface of zero total curvature. The distribution of the radiation heat flux to the body is determined. The effect of radiation on the flow of gas is considered, as an example, in the neighbourhood of the plane of symmetry of a conical body at the angle of attack.
