Abstract
Injection of plasma flow generated by a quasi-stationary plasma accelerator into a region with a magnetic field created by a series of ring current-carrying conductors forming a solenoid is considered. Numerical studies are carried out based on the set of magnetogasdynamic (MGD) equations represented in terms of the vector potential of the magnetic field, taking into account electrical conductivity, thermal conductivity, and radiation transport, provided that the plasma accelerator and ring conductors are located on the same axis. It is shown that small currents in ring conductors create a magnetic field inside the solenoid, which does not significantly affect the main stream, while simultaneously isolating it from the current coils as a result of the formation of a rarefied plasma layer separating the high-speed flow of dense plasma. Calculations of the MGD problem also show that the plasma flow within the solenoid is not accompanied by an increase in the temperature of the medium.
