【 摘 要 】

The effect of radiation on fluctuating hydro-magnetic natural convection flowof viscous, incompressible, electrically conducting fluid past a magnetizedvertical plate is studied; when the magnetic field and surface temperatureoscillates in magnitude about a constant non zero mean. The numericalsolutions 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 q ) in terms of amplitude and phase angle ofcoefficients of skin friction, rate of heat transfer and current density atthe surface of the plate. Moreover, the effects of these parameters ontransient coefficients of skin friction, rate of heat transfer and currentdensity have been discussed. The finite difference method for primitivevariable transformation and asymptotic series solution for stream functionformulation has been used to obtain the numerical solution of the boundarylayer flow field.
