ABSTRACT
To study the effect of thermal radiation on unsteady boundary layer flow with variable viscosity and thermal conductivity due to stretching sheet in porous channel in presence of magnetic field, a numerical model has been developed. The Rosseland diffusion approximation is used to describe the radiative heat flux in the energy equation. The governing equations reduced to similarity boundary layer equations using suitable transformations and then solved using shooting method. A parametric study illustrating the influence of the radiation R, variable viscosityε, Darcy number Da, porous media inertia coefficient γ, thermal conductivity κ, unsteady A parameters on skin friction and Nusselt number and Magnetic field parameter M.
