This paper presents the results of a theoretical and experimental study of the use of a pulsed discharge in water to obta.n.a strong acoustic wave in a liquid medium.A discharge with a current amplitude of 10 kA,a duration of 400 ns,and an amplitude pulsed power of 280 MW in water at atmospheric pressure created an expanding acoustic wave with an amplitude of more than 100 *** describe the formation of the discharge cha.n.l,an isothermal plasma model has been developed,which made it possible to calculate both the expansion dynamics of a high-current cha.n.l and the strong acoustic wave generated by *** calculations show that the number density of plasma in the cha.n.l reaches 10^(20) cm^(-3),while the degree of water vapor ionization is about 10%,and the cha.n.l wall extends with a velocity of 500 m s^(−1).The calculations for the acoustic wave are in good agreement with measurements.

The present paper investigates dispersed-phase flow structures of a dust cloud induced by a.n.rmal shock wave moving at a constant speed over a flat surface deposited with fine particles. In the shock-fitted coordinates, the general equations of dusty-gas boundary layer flows are formulated within the framework of a multi-fluid model and parametnc numerical studies of the carrier- and dispersed-phase flow fields are performed. The problem associated with crossing particle trajectories and the formation of local particle accumulation regions are solved by using the full Lagrangian method for the dispersed phase. The basic features of the near-wall two-phase flow under consideration including the role of Saffman force in the particle entra.n.ent and the development of discontinuities or singularities in the particle density profiles are discussed. The effects associated with account of the non-uniformity of particle size and the finiteness of the particle Knudsen numbers are studied in detail.

The present paper describes a.n.merical two-way coupling model for shock-induced laminar boundary-layer flows of a dust-laden gas and studies the transverse migration of fine particles under the action of Saffman lift force. The governing equations are formulated in the dilute twophase continuum framework with consideration of the finiteness of the particle Reynolds and Knudsen numbers. The full Lagrangian method is explored for calculating the dispersedphase flow fields （including the number density of particles） in the regions of intersecting particle trajectories. The computation results show a significant reaction of the particles on the two-phase boundary-layer structure when the mass loading ratio of particles takes finite values.
