Convective flow past an accelerated porous plate in rotating system in presence of magnetic field

Investigation on hydromagnetic convective flow of an incompressible homogeneous viscous liquid over an accelerated porous plate with suction/injection is presented using Laplace transform technique. The whole system is in a state of solid body rotation with constant angular velocity about z′-axis normal to the plate. The boundary conditions of the problem are of physical significance and thus the problem may have some important and interesting characteristic features of hydromagnetic spin up flows. The effects of suction/injection parameter on the velocity field and of Prandtl number on temperature field are graphically shown.
