Popis: | The theoretical study of detonation in two-phase media [1-3] and the results of experiments [4] indicate that the chemical-reaction zone behind the detonation wave is occupied by a compression wave and other structural phenomena, the nature of which is not fully understood. It is postulated in [i] that formation of the compression wave is mainly attributable to the increased gas density created by rapid particle vaporization, whereas in [3] the cause is assumed to be slowing of the gas by the particles due to the disparity between the velocities of the different phases. In the present note we consider the influence of the drag force between the two phases and the particle-vaporization products on the behavior of the parameters of the gas in the chemical-reaction zone behind a two-phase detonation front propagating through a mixture of fuel particles with a gaseous oxidizer. |
