UNSTEADY FLOW OF A CONDUCTING VISCOUS FLUID BETWEEN PARALLEL POROUS WALLS WITH HEAT TRANSFER.

The unsteady flow of a viscous incompressible electrically conducting fluid between two parallel permeable nonconducting moving walls is analyzed with allowance for heat transfer with the application of a uniform external magnetic field perpendicular to the walls. Both viscous dissipation and Joule heat are included in the heat-transfer equations. Explicit solutions expressed in terms of tabulated functions are obtained for a magnetic Prandtl number equal to unity.
