| Summary: | This study deals with the study of unsteady free convection in the stagnation point region of a three-dimensional body placed in an ambient fluid under the assumption of a step change in the surface temperature of the body. The non-linear coupled partial differential equations governing the free convection flow are solved numerically using an implicit finite-difference method for different values of the governing parameters entering these equations. Results for the flow and heat characteristics show that the transition from the initial unsteady-state flow to the final steady-state flow takes place smoothly. |
