The effect of viscous dissipation on fully developed mixed convection flow and heat transfer of immiscible fluids in a parallel plate vertical channel with symmetric and asymmetric wall heating conditions is studied analytically. Heat transfer occurs at the wall with an external fluid. Both conditions of equal and different reference temperatures of external fluid are considered. Separate solutions are matched at the interface using suitable matching conditions. The combined effects of buoyancy forces and viscous dissipation are analyzed by perturbation series method. The results are shown for various physical parameters such as perturbation parameter, viscosity ratio, width ratio, conductivity ratio and Biot numbers. It is found that perturbation parameter enhances the flow field whereas the viscosity ratio and conductivity ratio suppresses the flow field.
