Abstract: Direct numerical simulation of the problem of detonation of a free volume of a gas mixture is performed to study changes in the composition of the detonation products, determine the boundaries of applicability of the model of a mixture in chemical equilibrium, and verify the sufficient condition of the applicability of the model of a chemical-equilibrium mixture proved earlier. The results on the limits of applicability of the model of a chemical-equilibrium mixture obtained earlier using an approximate method are confirmed.

Keywords: model of a chemical-equilibrium mixture, detonation products, numerical modeling.
