Abstract
A numerical model for calculating superfast chemical reactions in mixtures under shock–wave loading is proposed. The effect of the impact velocity and chemical–transformation rate in a nonstoichiometric specimen of a low–porosity mixture of aluminum and sulfur is studied. Calculations were performed for impact velocities of 1000—2500 m/sec. The main characteristics of the process are given. It is found that flows occur when the unloading wave from the lateral surface of the specimen almost stops.
