Simulation of air shock wave using the equations of state for the Jones–Wilkins–Lee detonation products

The paper describes a mathematical model of the propagation of an air shock wave arising from the initiation of a substance with a high energy consumption and the subsequent flow of a mixture of air and gaseous detonation products. Various options for evaluating the correctness of the set of constants included in the equation of state for the Jones–Wilkins–Lee (JWL) detonation products are discussed. The results of model calculations based on the proposed technique, performed on structured and structurally irregular grids, are presented. The results obtained are discussed in comparison with analytical solutions of model problems and calculated data obtained using commercial packages.
