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.
