FLUCTUATING HYDROMAGNETIC NATURAL CONVECTION FLOW PAST A MAGNETIZED VERTICAL SURFACE IN THE PRESENCE OF THERMAL RADIATION

Abstract

The effect of radiation on fluctuating hydro-magnetic natural onvection flow of viscous, incompressible, electrically conducting fluid past a agnetized vertical plate is studied; when the magnetic field and surface emperature oscillates in magnitude about a constant non zero mean. The umerical solutions have been obtained for different values of radiation arameter (Rd) magnetic Prandtl number (Pm) magnetic force parameter S) Prandtl number (Pr) and surface temperature (θw) in terms of mplitude and phase angle of coefficients of skin friction, rate of heat ransfer and current density at the surface of the plate. Moreover, the ffects of these parameters on transient coefficients of skin friction, rate f heat transfer and current density have been discussed. The finite ifference method for primitive variable transformation and asymptotic eries solution for stream function formulation has been used to obtain he numerical solution of the boundary layer flow field.
