Discontinuous velocity fields in a hardening rigid-plastic material

The proposed model and the properties obtained on the surface of velocity discontinuity are used to study two processes of plastic deformation: lateral extrusion and torsion of a hollow disk. In both cases, analytical solutions are obtained. The limits of applicability of the solution to lateral extrusion are determined.

Calculation of a transport current from a nozzle with two-phase flow in the presence of a corona discharge

The operation of a source of charged aerosol particles which consists of a supersonic nozzle, a corona-forming needle-shaped electrode, and a device for injecting liquid droplets into a gas flow is considered. A theoretical model for two-dimensional, two-phase flow in the nozzle is considered. An algorithm of numerical calculation of such a flow is developed, and results of calculations of the electric transport current from the nozzle are given.

Spanwise propagation of turbulence in a boundary layer

The process of spanwise propagation of turbulence in a laminar boundary layer on a plate is numerically investigated. Three well-known turbulence models are considered.

Edge waves in a shallow fluid beneath a fractured elastic plate

It is shown that a fracture in an elastic plate floating on the surface of a shallow liquid layer is a waveguide along which wave energy can be transported. The edge wave velocity is less than the velocity of flexural-gravity waves. The existence of an antisymmetric edge wave mode depends on the Poisson's ratio of the elastic plate. Moscow.
