EFFECTS OF END CURRENT LOOPS ON THE VELOCITY PROFILE IN A MAGNETO- HYDRODYNAMIC CHANNEL
The effect of the end-current loops on the velocity profile in a magnetohydrodynamic flow was investigated for incompressible inviscid flow in a rectangular channel. The end-current loops interact with the applied magnetic field to produce Lorentz forces. In the entrance region of the channel, the Lorentz forces vary in magnitude and direction. This variation of the Lorentz forces causes the velocity of the fluid to increase near the walls of the channel and to decrease near the center. The ratio of the changes in velocity to the initial velocity is directly proportional to the interaction parameter sigma B? omicron /sub o//?U/sup 2/. For a value of sigma B?/sub o//?U/sup 2/ = 0.25, the maximum change in velocity is 10% of the initial velocity. (auth)
