Abstract:
The effect of radiation on fluctuating hydro-magnetic natural
convection flow of viscous, incompressible, electrically conducting fluid past a
magnetized vertical plate is studied; when the magnetic field and surface
temperature oscillates in magnitude about a constant non zero mean. The
numerical solutions have been obtained for different values of radiation
parameter (Rd) magnetic Prandtl number (Pm) magnetic force parameter
(S) Prandtl number (Pr) and surface temperature ( w θ ) in terms of
amplitude and phase angle of coefficients of skin friction, rate of heat
transfer and current density at the surface of the plate. Moreover, the
effects of these parameters on transient coefficients of skin friction, rate
of heat transfer and current density have been discussed. The finite
difference method for primitive variable transformation and asymptotic
series solution for stream function formulation has been used to obtain
the numerical solution of the boundary layer flow field
