【 摘 要 】

Stationary plasma flows obtained by using numerical solutions of corresponding stationary problems in curved coaxial channels are considered. It is supposed that plasma interacts with own azimuthal magnetic field. The main attention of the paper is focused on accelerating transonic flows, which attract a considerable interest in the theory of plasma accelerators. It was demonstrated that a curvilinear configuration of a channel makes the significant contribution to distributions of basic plasma parameters.
