Abstract: A theoretical investigation on the flow of nonlinear MHD, laminar, viscous, incompressible boundary layer fluid with thermal radiative heat transfer and variable properties past a stretching plate was carried out. The liquid is taken to be gray, absorbing, emitting but with non-scattering medium. The main nonlinear equations governing the flow are reduced to ordinary differential equations by using appropriate similarity variables and quantities. The obtained nonlinear equations are computational solved by applying shooting techniques coupled with Nachtsheim-Swigert method for asymptotic satisfaction of boundary conditions by fourth order Runge-Kutta scheme. The computational results for momentum and heat distribution are gotten for various values of the emerging parameters. The results for the coefficient of skin friction and dimension less heat gradient are likewise obtained for different physical parameters values. From the study, it was observed that the parameters which enhance the heat source terms decreases the fluid viscosity and causes increase in the flow rate. Also, parameter that reduces heat source terms encourages viscosity which resulted in retardation of the fluid velocity.
