Pulsed discharge of a two-phase medium from a bounded duct capable of longitudinal motion

The regularities of the initial stage of discharge of a two-phase disperse medium from a bounded duct capable of longitudinal motion are established. Numerical results obtained within the framework of a medium with nonequilibrium for velocities and temperatures are compared with analytical solutions of the equilibrium mechanics of disperse systems for the case where the characteristic time of the process is of the order of the characteristic times of velocity and thermal relaxation or smaller.
