Abstract

Issues raised are free convection flow of viscous-elastic through a porous sphere with the completion of numerically using central finite difference method. The free convection flow can described continuity equation, momentum, and energy. Further, governing equations dimensionless form will be transformed into a non-dimensional equation and transformed again into a non-similar equations. The results of this research about the impact of viscoelastic parameter (K), Prandtl number (Pr), and porosity (P) on the flow velocity profile (f \\) is inversely proportional , However effect of heat generation parameter (#947) on the flow velocity profile (f \\) is inversely proportional. And the effect of the viscoelastic parameters (K) and heat generation (#947) to the flow temperature profile (#952) is proportional, However the effect of Prandtl number (Pr) parameter and porosity (P) on the flow temperature profile (#952) is inversely proportional.
