| Popis: | This article considers the laminary combustion of a hybrid gas suspension consisting of a gaseous combustible, an oxidizer, and an inert gas, as well as particles capable of interacting with the gas-phase oxidizer. The mathematical model takes into account the thermal expansion of the gas and its related relative motion of particles. The problem has been solved numerically in dimensionless variables. The dependences of the steady velocity of the flame front on the initial concentration of the combustible in the gas phase at various values of the parameters of the dispersed phase are presented. A comparison has been made between experimental and calculated data for a gas suspension consisting of a gaseous oxidizer, an inert gas, and reactive particles. |
