Реферат: | eng: On the basis of numerical simulation, the processes of whistler, Alfven and collisionless shock waves generation are investigated in the interaction of high-speed plasma flows in a magnetic field. The statement of the problem corresponds to the conditions of laboratory experiments at the KI-1 facility (ILP SBRAS) [1]. The numerical model is based on the kinetic description of the ion plasma component and the gas-dynamic approximation for magnetized electrons (hybrid model) [2]. To solve the Vlasov kinetic equation, the author's modification of the particle method in the cell (PIC) is used. The structure of the generated perturbations is analyzed as a function of the plasma parameters and a magnetic field. The characteristics of shock waves for the regimes of a multistream flow formation and the mechanisms of ion acceleration in the front of a shock wave are studied. © 2018 Institute of Physics Publishing.
