Effect of nonuniform conductivity in the boundary layer at the electrode wall on local characteristics of an MHD generator with a diagonal electrode configuration and a subsonic stream
A method for calculating the performance characteristics of an MHD generator with diagonal connection of the electrodes is discussed and the results are presented. The method allows for nonuniform conductivity in the boundary layers at the electrode wall, nonideal insulators, and possible intrusion of the electrodes into the flow. The range of governing parameters is the following: relative temperature of the electrode wall T-bar/sub w/=T/T/sub 0/=0.5-1.0, relative thickness of the boundary layer delta-bar=2delta/y/sub 0/=0.1-0.3, degree of electrode intrusion into the flow l-bar=l/delta=0-1.0, Hall parameter ..beta..=0--10. The effect of these parameters on the power, the load coefficient, the angle of electrode connection, and the current and potential distribution in the plasma is shown. (AIP)
