Abstract:
The numerical modeling methods were used to test the reduced kinetic scheme of detonation combustion of aluminum particles in air, taking into account the formation of gaseous and condensed aluminum suboxides. The results of testing the numerical algorithm using parallel programming methods and the Runge–Kutta numerical scheme of different orders in time are presented. The results of calculating the cellular detonation of aluminum suspensions in air of different dispersion and loading are presented. It is shown that the degree of regularity of the cellular structure and the cell size are determined by the size and loading of the particles. The detonation velocity depends weakly on the particle size and depends significantly on the loading. The results are in the good agreement with the experimental and calculated data of other authors.
Keywords:numerical modeling, heterogeneous detonation, gas suspension of aluminum particles, reduced kinetic model.
