Abstract

The unsteady hydromagnetic free convection flow of a viscous incompressible and electrically conducting fluid generated by an impulsively moving vertical plate subject to constant heat flux at the plate has been considered. The dimensionless parameters governing the problem are the Prandtl number, the Grashof number and the Hartmann number. An exact solution has been obtained for this problem using Laplace transform. Velocity and skin friction of the flow have been presented for water, and the influence of the governing parameters has been discussed. In particular, the magnetic field has a retarding effect on the velocity while skin friction at the plate increases with it.
