| Abstract: |
| In this article, author has examined the unsteady flow over a rotating stretchable disk with deceleration. The highly nonlinear partial differential equations of viscous fluid are simplified by existing similarity transformation. Reduced nonlinear ordinary differential equations are solved by homotopy analysis method (HAM). The convergence of HAM solution is also obtained. A comparison table between analytical solutions and numerical solutions are also presented. Finally, the results are found for useful parameters i. e disk stretching parameter, unsteadiness parameter. |
