UNSTEADY-FLOW BETWEEN 2 DISKS WITH HEAT-TRANSFER IN THE PRESENCE OF A MAGNETIC-FIELD

The motion of an electrically conducting fluid film squeezed between two parallel disks with heat transfer in the presence of a magnetic field applied perpendicular to the disks is studied. Attention is given to the case where a similarity solution can be obtained. Approximate analytic solutions are given and a numerical solution to the resulting nonlinear ordinary differential equations for a wide range of values of the three independent parameters which influence the motion is presented. Special attention is given to the effects of squeezing and magnetic forces on heat transfer. The results establish that while squeezing has considerable effects on heat transfer, the effects of magnetic forces are negligible.
