Effects of viscous dissipation and joule heating of magnetohydrodynamics (MHD) convective nano fluid heat transfer over a flat porous plate

In the present investigation, we studied the effects of Viscous Dissipation and Joule Heating of magnetohydrodynamic (MHD) convective heat transfer over a flat porous plate. The governing partial differential equations is expressed into a nonlinear partial differential equation, using a suitable similarity transformation. A semi analytical method of Homotopy Parturbation was applied to solve the equation and the obtained numerical solution for the velocity, temperature and other parameters of the nano fluid are discussed and represented graphically. Also, the effect of other parameters on the velocity and temperature profiles are also presented.
