The purpose of the present paper is to report the results of numerical and experimental studies of supersonic flows in a diagonal type MHD generator. Numerical analysis has been carried out using one-dimensional conservation equations coupled with Maxwell's equation and the generalized Ohm's low. It is shown that when the loading factor increases, m the Mach number in the channel decreases in the case of an absolute value of a diagonal coefficient smaller than a Hall coefficient, and the Mach number increases in the opposite situation cap. The limiting length of the channel for choking decreases with an increase in he interaction parameter and friction coefficient. The experimental results show the validity of the numerical analysis.
