• Homotopy analysis method

The similarity transform for the steady free convection boundary layer flow of a non-Newtonian fluid (Casson model) with variable wall temperature on a horizontal plate gives a system of nonlinear ordinary differential equations which is solved analytically by applying a newly developed method namely the homotopy analysis method (HAM). The velocity and temperature profiles are obtained and the influence of Prandtl number and various physical parameters of the problem on these distributions are discussed in detail and are illustrated graphically through a set of graphs. The validity of our solutions is verified by the numerical results.
