Abstract

In this paper, the problem of boundary layer flow and heat transfer of MHD power-law fluid     over a porous sheet in the presence of partial slip is investigated numerically. We assume a temperature dependent thermal conductivity and slip conditions are employed in terms of shear stress. The suitable similarity transformations are used, to transform the governing partial dif- ferential  equations  (PDEs)  into  a  system  of  nonlinear  ordinary  differential  equations  (ODEs). The resulting system of  ODEs  is  solved  numerically  using  Matlab  bvp4c  solver.  The  numerical values obtained for the velocity and temperature depend on power-law index, slip parameters, permeability, suction/injection parameter, Prandlt number and  Nusselt  number.  The  effects  of various  parameters on  the  flow and  heat  transfer characteristics are  presented through graphs and tables and discussed from physical point of   view.
