    This work is devoted to the theoretical calculation of the processes of compression and energy release in the target by a combined action of a system of pulsed jets and intense laser radiation using a magnetic inertial plasma confinement method. A mathematical model, a numerical method, and a computational algorithm are developed to describe plasma-physical processes occurring in various types of high-temperature installations with high density. The results of the calculation of the hybrid effect of intensive energy flows on a cylindrical target are presented. The main gas-dynamic and radiative parameters of the compressed target plasma are found.

    One of the main obstacles to the uniform laser compression of a fusion target is the plasma formation instability (the Rayleigh –Taylor instability is the most dangerous). In all the schemes considered, the impulsive character is important. In this case, not all possible plasma instabilities are dangerous, but only those that most rapidly increase with time (for example, Rayleigh – Taylor instability).

    A statement of the problem is presented and numerical modeling of plasma-gas-dynamic processes in the capillary discharge plume is performed. In the developed model, plasma dynamic processes in a capillary discharge are determined by the intensity, duration of plasma formation processes in the capillary discharge channel, and thermodynamic parameters in the surrounding gaseous medium. The spatial distribution of temperature, density and pressure, radial and longitudinal velocities of pulsed jets of several capillary discharge channels is presented.
