Краткое описание

Within the frame of mathematical model for one-velocity tow-phase medium (gas with solid reacting aluminum particles) a function for energy release due to aluminum particle combustion is specified and mass and energy exchange terms in equation systems describing the model are defined.
The generalized kinetics of aluminum ignition and combustion including the oxide film growth, combustion grade into the vapor-phase regime and aluminum burning-out is presented. An algorithm to calculate thermodynamics and kinematics parameters at the detonation wave front and behind the detonation wave front including the energy release due to aluminum particle combustion is described.
A procedure to calculate the initial concentration for oxidizing elements, maximum part of aluminum reacted and its combustion heat in the detonation products of different oxidizer concentration is presented. The numeric coefficients to determine the closing equations of the aluminum particle combustion model in detonation products are selected and proven.
A computer code with graphic interface for numerical simulation of 3D non-stationary shock-wave processes resulted from detonation of multi-phase explosives containing solid phase combusting behind the detonation front has been developed by the authors of the presented paper. The test problem solutions are presented.
