Electrical and Pressure Losses in a Magnetohydrodynamic Channel due to End Current Loops

摘要

The problem of end losses in a magnetohydrodynamic flow has been studied for incompressible inviscid flow in a rectangular channel. Termination of the mag¬netic field at the ends of the electrodes leads to electrical losses which increase with decreasing aspect ratio of the electrode section of the channel. The losses are also (abstract continued) increased with increasing values of the generator coefficient. These electrical losses can be corrected by extensions of the magnetic field beyond the electrode region, but these corrections adversely affect the net pressure change through the device,
