| Abstract: | A study is made of one-dimensional nonstationary problems of the combustion and detonation of aerosuspensions of unitary fuels or propellants, which contain the oxidant as well as the combustible material (gunpowder, high explosives). A numerical analysis is made of the damping of the convective combustion which occurs at relatively low mass concentrations of the fuel; the critical concentration dividing the damped and the detonation regimes is determined. It is shown that the realization of the damped or detonation regime of convective combustion at a given concentration is completely determined by the gas dynamics of the relative motion of the gas and the particles (two-velocity effect), this being governed by the coefficient of friction.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 22–27, January–February, 1981. |
