Abstract
Summary form only given. The task of simulation of the magnetohydrodynamic process in the nonuniform gas-plasma flow driving recombinated plasma clots is solved. The different types of diffusive discharge present in the noble gas flow simultaneously. The glow discharge exists in the driving low-ionized gas and the nonequilibrium arc discharge-in the high-ionized plasma clot. For the process simulation the universal kinetic model of the nonequilibrium plasma of noble gases is created, describing the multilevel ionization and recombination kinetics in the framework of the modified diffusional approach. The model takes into account the most important processes for the dense low temperature plasma: collision excitation and de-excitation and the processes with the participation of the molecular ions. The deviation of the electron energy distribution function from the Maxwellian one was taken into account also. The kinetics equation included the ambipolar diffusion and the wall losses of electrons. This model allowed to describe the both types of discharge uniformly.
