Falkner-Skan transformations will reduce the governing partial differential equations into two non-linear partial differential equations. These equations are solved by HAM and theconvergence of this is studied by using the Domb Sykes plot. The effect of suction and injectionare studied on the velocity and temperature distribution and are depicted in a graph. It is alsoobserved that for large values of suction and injection flow separation exists in boundary layerregion. Pade approximation is also applied to HAM series solution which helped us to identifythe singularities. Convergence is verified by plotting h curve for all the three cases suction,injection, and no suction for both velocity and temperature.
