Popis: Numerical analysis of the distribution of electric currents in a plasma medium, with the Hall effect taken into account, has been conducted in many works dedicated to studying intrachannel flows in various MHD devices. The aim of the present paper is to study the peculiarities of the current distribution in stationary underexpanded plasma jets flowing into a neutral medium, with the magnetic field applied in such a manner as to be directed along the jet axis. This topic has been virtually neglected in the literature although its study would be of interest in designing and using certain types of MHD engines and accelerators. Although the problem seems to be somewhat simpler than that presented because of the absence of electrodes in the computational domain, it nevertheless has its own special features which are due to the fact that it has a free boundary and that the jet is not limited down the flow.
