analytical solution to study of mhd visco elastic fluid flow through porous medium over an exponential stretching sheet

Abstract

we study the steady two dimensional electrically conducting visco-elastic fluid flow and heat newlinetransfer through porous medium over an exponentially stretching sheet in presence of uniform transverse magnetic field. newlineThe governing boundary layer equations are converted into non-linear ordinary differential equations by using suitable newlinesimilarity transformations. The obtained non linear ordinary differential equations are solved analytically using newlineHomotopy Analysis Method (HAM). The results are analyzed graphically for various values of physical parameters like newlinevisco-elastic parameter, magnetic parameter, porosity parameter and Prandtl number. The results are compared with the newlineexisting results in literature and are seen in good agreement. newline
