SIMULATION OF GAS DETONATION PROPAGATION IN A MEDIUM HAVING VARIABLE CHEMICAL COMPOSITION

Within the framework of a quasi-one-dimensional approximation, a mathematical model of the propagation of a detonation wave in a tube fi lled with explosive gas mixture with spatially variable chemical composition has been formulated, and the respective problem has been solved numerically. The shift in the chemical equilibrium of detonation products as well as the friction and heat removal losses were taken into account. The proposed mathematical model allows one to describe steady-state (of Chapman–Jouguet) and over-compressed detonation regimes.
