Abstract
The behavior of a magnetohydrodynamic channel, with finite segmented electrodes, when a plasma in a nonequilibrium state and with tensor conductivity flows through it with constant (uniform) velocity is presented. The nonequilibrium effect is taken into account by assuming the plasma electrical conductivity to be a linear function of the current density. The problem, which is highly nonlinear, is solved by expanding in powers of the proportionality constant to obtain a recursive set of linear equations. In this paper only the zeroth- and first-order solutions are presented. They are obtained numerically. For the cases studied, no shorting due to leakage between adjacent electrodes exists. Despite this inclusion of the nonequilibrium effect causes a reduction of the Hall (axial) electric field.Keywords
