The governing nonlinear equations are first modelled and then solved analytically by utilizing homotopy analysis method (HAM). The convergence of the developed series solution is established. The influence of the important parameters of interest is seen on velocity.}, number={1-2}, journal={The Nucleus}, author={Sajid, M.}, year={2020}, month={Jul.}, pages={1–5} }
