Abstract

This paper considers the extended classical Blasius and Sakiadis equations, by considering a uniform free stream parallel to a fixed or moving flat plate, which has more practical significance. It is assumed that the plate is subjected to a constant heat flux, and moves in the same or opposite direction to the free stream. The resulting system of nonlinear ordinary differential equations is solved numerically using a finite-difference method. Numerical results are obtained for the skin friction coefficient and the local Nusselt number as well as the velocity and temperature profiles for some values of the governing parameters, namely the velocity ratio parameter and the Prandtl number. The results indicate that dual solutions exist when the plate and the free stream move in the opposite directions.
