AB - <p>In this paper, we consider the dynamics of a large-scale cloud formed in strong explosions in<br>an inhomogeneous atmosphere, with allowance for turbulent mixing and adiabatic expansion.<br>Numerical simulation is carried out on the basis of the solution of the three-dimensional filtered<br>non-stationary Navier-Stokes equation, the continuity equation, the concentration equation, the<br>enthalpy equation, and the equation of state for compressible media. The modified solver is based<br>on the OpenFOAM mathematical physics library. To close the basic equations, a viscous model of<br>turbulence is used. The change in the size of the cloud in the atmosphere is determined depending<br>on the thermodynamic parameters. The calculation of the explosion energy calculated for the<br>remainder of the Proton-M carrier rocket was made.</p>
