Main Article Content
In this paper, steady two dimensional MHD free convective boundary layer flows of an electrically conducting nanofluid over a nonlinear stretching sheet taking into account the chemical reaction and heat source/sink are investigated. The governing equations are transformed into a system of nonlinear ordinary differential equations using suitable similarity transformations. Analytical solution for the dimensionless velocity, temperature, concentration, skin friction coefficient, heat and mass transfer rates are obtained by using homotopy analysis method (HAM). The obtained results show that the flow field is substantially influenced by the presence of chemical reaction, radiation and magnetic field.
