ON THE ACCELERATION OF MAGNETOGASDYNAMIC CHANNEL FLOWS THROUGH THE SONIC VELOCITY

Abstract

The possibility of passage through the sonic velocity is examined for the magnetogasdynamic flow through a diverging, straight-walled channel. In addition to the usual assumptions of continuum MGD, the electrical conductivity is assumed to be small, but the effect of Hall cur rent is included. A number of different cases arise, depending on whether or not one or more parameters vanish or are small. Numerical re sults for the case where the Hall current van ishes, and the problem becomes analogous to the gasdynamic source, indicate the sonic point can be placed anywhere along the channel by proper selection of the electric and magnetic field strengths and boundary conditions.
