Abstract

The computational study of the combined effects of radiation and hydromagnetics on natural convection flow of, viscous, incompressible, electrically conducting fluid past a magnetized permeable vertical plate was presented. The governing non similar equations were solved by using (i) finite difference method for entire value of suction parameter ξ and asymptotic solution for small and large value of ξ numerically. The effects of varying the Prandtl number Pr,magnetic Prandtl number P_m, magnetic force parameter S, radiation parameter R_d ,and surface temperature θ_w on coefficients of skin friction, rate of heat transfer and current density were shown in graphical form and as well as in tables. Finally, an attempt was made to examine the effects of above mentioned physical parameters on velocity profile, temperature distribution and transverse component of magnetic field.
