| Abstract: |
| This work is focused on the steady boundary layer flow and heat transfer near the stagnation point of plane and axisymmetric bodies towards a stretching sheet. The analytical solutions of the velocity and temperature distributions are obtained for the various values of the ratio of free stream velocity and stretching velocity, heat source parameter, Prandtl number and dimension index in the series forms with the aid of homotopy analysis method (HAM). Convergence of the series is explicitly discussed. The effects of all the parameters mentioned above were more pronounced for plane flows than for axisymmetric flows. |
