Numerical solution to the problem of the decay of the high-temperature region of a radiating gas for different initial distributions of internal energy
Abstract
Radiative heat transfer plays a significant role in the development of the initial perturbation during concentrated and drastic energy release in a gas. This paper presents a theoretical analysis of the problem of the decay of the high-temperature region of a radiating gas which models the aforementioned process irrespective of the nature of the energy-release source. The equations of radiative gas dynamics are integrated numerically; model power dependences on the thermodynamic parameters are used for the absorption coefficient and the radiation-source function. It is shown that, for sufficiently small dimensions of the energy-release region, solutions of the decay problem for different initial distributions of the internal energy practically coincide for short periods of time.
