Mixed Convection and Radiative Heat Transfer of MHD Casson Fluid Flow by a Permeable Stretching Sheet with Variable Thermal Conductivity and Lying in Porous Medium

This work investigates the mixed convection radiative heat transfer of electrically conducting Casson fluids. The fluid flows past a permeable stretching sheet lying in the porous medium. The heat transfer involves variable thermal conductivity and convective boundary conditions. The formulation of the problem is primarily in the form of the non-linear partial differential equations. These governing equations are transformed to their ordinary differential form by employing similarity transformation. The resulting equations are then solved numerically by classical Rung-Kutta method. Computations have been made for some representative values of the pertinent parameters to elaborate the physical behavior of flow and thermal characteristics.
