STAGNATION-POINT FLOW AND HEAT TRANSFER OVER A HYPERBOLIC STRETCHING SHEET
ABSTRACT
In this study, steady two-dimensional boundary-layer stagnation-point flow of viscous incompressible fluid over a hyperbolic stretching sheet and heat transfer in it have been investigated. The governing equations of the flow problem are transformed into dimensionless partial differential equations using nondimensional variables. A numerical solution of the obtained partial differential equations is done by using an implicit finite difference scheme known as the Keller-Box method. The effects of the velocity ratio parameter a/c and the Prandtl number Pr on the velocity profile, temperature profile, local skin friction coefficient, and the local Nusselt number have been studied and shown graphically. It is observed that the heat transfer rate increases rapidly in the presence of the velocity ratio parameter a/c as compared to the absence of the velocity ratio parameter.
