End losses in a magnetohydrodynamic channel: Dc channel with fluid having large magnetic reynolds number

The Wiener-Hopf technique is used to solve for the electric field in a dc magnetohydrodynamic generator channel, under mixed boundary conditions. The ohmic losses are then evaluated. No restriction is made on the magnitude of the magnetic Reynolds number of the working fluid. Two problems of the semi-infinite generator section are solved, namely when the end region is at the channel entrance and when it is at the channel exit. Also the finite generator section problem is discussed.
