INVISCID FLOW OF RADIATION DUSTY GAS DYNAMICS.

The effects of radiation pressure and radiation energy on the flow of an ideal radiating dusty gas at very high temperature are studied. The most important parameter is the ratio of radiation pressure to the pressure of the mixture (gas plus dust), the radiation pressure number R//p. Even though some basic phenomena for this present case are similar to those of ordinary gas dynamics, many new phenomena occur. The maximum possible velocity of a dusty gas from a given stagnation condition depends on stagnation temperature and stagnation density of the dusty gas. It also depends on the concentration of the dust particles. The jump of temperature across a normal shock is proportional to the square root of the shock Mach number.
