HEAT AND MASS TRANSFER FLOW IN AN ELECTRICALLY CONDUCTING FLUID OVER A PERMEABLE STRETCHING SHEET WITH OHMIC DISSIPATION

An analysis has been performed to study the combined effect of heat and mass transfer characteristics in an electrically conducting fluid over a permeable stretching sheet in the presence of Ohmic dissipation. The arising nonlinear coupled partial differential equations are reduced to a set of coupled nonlinear ordinary differential equations which are solved analytically by homotopy analysis method for two sets of prescribed boundary conditions, i.e., (1) the wall with prescribed second-order power law temperature and second-order power law concentration and (2) the wall with prescribed second-order power law heat flux and second-order power law mass flux. The effects of emerging physical parameters on the velocity, temperature and concentration profiles are interpreted. Numerical data for skin friction coefficient, Nusselt number, and Sherwood number have been tabulated for various values of the parameters. The results are compared with known numerical solutions from the literature in a limiting sense.
