Abstract: An approach that permits one to analyze the process of explosion of liquid fuel components is described in the context of the two-phase equilibrium approximation, with allowance for the volume occupied by the fluid particles. The numerical implementation was carried out in the two-dimensional approximation based on the scheme of S. K. Godunov. The calculations make it possible to estimate the distribution of the gas dynamic parameters at different times.

Keywords: upper stage, components of liquid fuel, explosion, gas-liquid mixture, mixture model.
