Quasi-Linearization approach to effects of heat source/sink on MHD flow of non-Newtonian power-law fluid past a continuously moving porous flat plate with heat flux and viscous dissipation

The MHD flow and heat transfer of the non-Newtonian power-law fluid flow past a continuously moving flat porous plate in the presence of heat source/sink with heat flux and viscous dissipation is studied. The non-linear partial differential equations governing the flow and heat transfer are transformed into non-linear ordinary differential equations using appropriate transformations and then solved numerically by an implicit finite difference scheme. The solution is found to be dependent on various governing parameters including magnetic field parameter M, power-law index n, suction/injection parameter fw, heat source/sink parameter S, Radiation parameter Rd and Eckert number Ec. A systematical study is carried out to illustrate the effects of these major parameters on the fluid velocity and temperature distribution in the boundary layer. The results for the skin friction coefficient, rate of heat transfer and the local Nusslet number are tabulated and discussed.
