A theoretical study of plasma parameters of a high-current discharge in a limited volume (in the discharge chamber) of a body moving in an electrodynamic accelerator (railgun) has been performed. The experiments have shown that in the case of a cylin

The stabilization of a plasma jet in a vortex chamber as a result of the return of the turbulent moles coming out of this jet and back into it was analyzed with account for the nonuniformity of the circumferential velocity of the vortex, the heat tra

A jet model based on approximations of velocities, satisfying the continuity equation, and on the integral momentum equation is presented. The solution for the jet dynamics turned out to be nonmonotonic: as an obstacle recedes over a distance larger

The paper analyzes the Ruff–Wiederhorn hypothesis that several particles participate in one erosion event in a stream of solid particles for plastic materials. The proposed erosion model is based on two kinds of particles, primary and secondary, th

A plastic particle will adhere to a substrate after collision if the work of adhesion in the contact area exceeds the elastic rebound energy. The plastic deformation of the particle decreases the elastic strain energy and increases the probability of
