Аннотация
Investigated was nonadiabatic propagation of cellular structures in conditions of unsteady infiltration-mediated combustion in porous media. The size and structure of cellular hot spots was found to be a non-linear function of governing parameters, including heat sink into environment. Quasi-stationary dynamics of cell propagation in near-critical conditions was simulated in terms of a quasi-3D mathematical model. The evolution of cellular combustion was investigated as a function of heat losses. Experimental data for cellular combustion of Ti powders in a slit-like reactor were found to agree with predictions of the model.
