Abstract

The influence of radiation on a steady, one dimensional flow is considered. Only radiative heat transfer is taken into account; viscosity, heat conduction and mass diffusion are neglected. It is further assumed that the radiative heat transfer is adequately described by the quasi equilibrium theory relative to a grey gas.

Under these conditions, the velocity of the fluid satisfies an integral equation which has been investigated by various methods. It is shown that under certain conditions the influence of radiation alone is not sufficient to smooth out the shock profile and a discontinuity in velocity still appears; mass diffusion processes are dominant in these cases.
