Analytical solution of non -Newtonian second –grade fluid flow by VIM and ADM methods on a stretching sheet

This study aimed at investigating the variation of heat transfer and velocity changes of the fluid flow velocity along the vertical line on a plane drawn from both sides. To this end, several parameters were evaluated, including the prandtel and heat transfer coefficient and the fluid flow rate at the boundary layer range of ƞ=۰ through ƞ=۱ using two Adomian decomposition and variation iteration methods, followed by solving their nonlinear differential equations. Next, the results were compared with the numerical method. The results revealed that by increasing the distance from the plane surface in line with the vertical direction of the velocity parameter value increased, and gradually reached a constant value. However, regarding heat transfer, the heat transfer rate reduced when moving from the plane surface to the top.
