Abstract

In this paper, the evolution of a cloud under the influence of the buoyancy force is considered, taking
into account turbulent mixing and adiabatic expansion. Numerical simulation is carried out on the
basis of the solution of the three-dimensional filtered non-stationary Navier-Stokes equation, the
continuity equation, the concentration equation, the enthalpy equation, and the equation of state
for compressible media. The modified solver is based on the OpenFOAM mathematical physics
library. To close the basic equations, a viscous model of turbulence is used. The dependence of the
height of the lifting of the fireball in the atmosphere on the thermodynamic parameters, during
the explosion of the Proton-M rocket carrier on July 2, 2013, was obtained.
