Free convection effects on hydromagnetic oscillatory flow in rotating porous medium with constant heat sources

Unsteady hydromagnnetic free convection flow of an incompressible liquid through a porous medium past an infinite isothermal vertical porous plate with constant heat source in a rotating system has been analysed. The transient velocity, transient temperature distribution, transient rate of heat transfer, mean skin friction, phase and amplitude of skin friction are discussed. The effects of magnetic parameter (M), Grashof number (Gr), heat source parameter (α), Ekman number (E), permeability parameter (k) and frequency parameter (ω) on flow field are shown and discussed.
