“…A particular case of vortex structures is a plasma toroidal vortex or a ring vortex [10][11][12][13]. One of the main and important properties of the toroidal vortex is that it travels in an unbounded medium before its decay long distances compared to a cloud (plasma, gas, liquid) of the same size as the vortex.…”

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. RUSSIAN JOURNAL OF NONLINEAR DYNAMICS, 2019, 15(4), 543-550 544 V. V. Kuzenov, S. V. Ryzhkov structures (which form near the boundary of a pulsed jet) and a capillary discharge torch in the air atmosphere.When carrying out these calculations, the capillary discharge channel was not considered, and the gas-dynamic parameters flowing into the flooded space of the pulsed plasma jet were estimated as follows. In a first approximation, the mathematical model of plasmodynamic processes inside a channel of a capillary discharge can be constructed from the condition that the energy deposited from a capacitive storage is emitted by an optically dense plasma, and all electrical energy is transferred to the thermal energy of the plasma, which expires with sound velocity through a section of a capillary discharge.Plasma-dynamic processes occurring in a plasma torch of a capillary discharge can be determined using the system of equations of viscous two-temperature radiation plasma dynamics. The numerical method for the equations of plasma dynamics is based on the method of fractional steps. The numerical solution is also described in [3,4].

“…A numerical technique for constructing regular curvilinear adaptive grids in arbitrary domains is formulated. This technique makes it possible to construct an adaptive (to the boundaries of the computational zone and peculiarities of solving mathematical physics problems [30][31][32][33][34][35][36]) computational grid by solving elliptic partial derivative equations and with the help of special adaptation algorithms. On the basis of the developed numerical codes, numerical simulations of two points of the ARIAN 5 rocket flight trajectory were performed.…”

This paper considers the problem associated with the numerical simulation of the interaction between the cocurrent stream occurring near a monoblock moving in the gas medium and solid fuel combustion products flowing from a solid fuel rocket engine (SFRE). The peculiarity of the approach used is the description of gas-dynamic processes inside the combustion chamber, in the nozzle block, and the down jet based on a single calculation methodology. In the formulated numerical methodology, the calculation of gas-dynamic parameters is based on the solution of unsteady Navier–Stokes equations and the application of a hybrid computational grid. A hybrid block-structured computational grid makes it possible to calculate gas flow near bodies of complex geometric shapes. The simulation of the main phase of interaction, corresponding to the stationary mode of rocket flight in the Earth’s atmosphere, has been carried out. A conjugated simulation of the internal ballistics of SFRE and interaction of combustion products jets is conducted.

This research is devoted to the calculation and theoretical analysis of physical processes in the powerful electric discharge sources of UV radiation and shock waves with required and controlled technical and physical characteristics. Based on the calculations, the processes of converting the initially stored electromagnetic energy into internal, kinetic, magnetic and radiation energy formed in the electro-discharge plasma sources of plasma formation were studied, and the interactions of discharged plasma and its radiation with matter in different aggregate states were also studied. All the main magneto-plasma dynamic and radiative parameters of plasma formation in the electric discharge sources of UV radiation and shock waves are obtained.
