Two-component radiation-gasdynamic model of a turbulent fireball

Abstract

A two-dimensional computational model of the dynamics of a radiating turbulent fireball that can form in accident-induced explosion of a rocket at the launching position or in flight is presented. The model is based on the system of Navier-Stokes equations, two-component diffusion of explosion products (water vapor) in the ambient air, and a multigroup system of equations of thermal radiation transfer. The possibility of employing three models of turbulent mixing — the Prandtl model, the Penner-Haselman-Edwards model, and the Launder-Spalding model — is investigated.
