A numerical analysis used to simulate forced convection heat transfer of incompressible Jeffery’s fluid past an inclined vertical plate with presence of Naiver slip and Newtonian heating effects. The governing partial differential equations are remodeled into ordinary differential equations by using non-similarity transformation. The ensuing differential equations are resolved numerically by using centered finite difference technique (Keller Box Method). The results of flow and heat analysis on the local skin friction coefficient and local Nusselt number profiles are given diagrammatically. Results shows that Navier slip parameter enhance the heat transfer rate and suppress the friction at wall, but opposite effect can be found the presence of Newtonian heating. The simulation is relevant to polymer coating thermal processing.
