| Abstract: | One-dimensional plane pulsed joint motion of a gas phase and a disperse phase in the presence of friction of the latter against
the duct walls are studied numerically using the model of a heterogeneous medium. It is established that two qualitatively
different regimes of motion are possible, depending on the initial conditions in a high-pressure chamber and the value of
the friction factor. It is found that the powder exit velocity is self-similar with respect to friction.
