Studying the influence of relative motion of suspended inert particles on the rate of the gas mixture combustion front

The dependence of the burning rate of a gas mixture with inert particles on concentration of fuel taken in the stoichiometric ratio with the oxidant and under the lack of fuel is studied. The compared calculation results wer obtained based on two mathematical models: with allowace for the thermal expansion and without regard to it. The dependences of the propagation velocity of the combustion front on the size and mass concentration of the inert particles were obtained at different initial concentrations of fuel.
