Abstract

The mathematical modelling for forced convection boundary layer flow at a
forward stagnation point with constant wall temperature (CWT) and constant heat flux
(CHF) is considered. The boundary layer equations are transformed to similarity equations
using similarity transformation. The transformed equations are solved numerically using a
numerical scheme known as the Keller-box method. Numerical solutions are obtained for
the heat transfer coefficient, surface temperature as well as velocity and temperature
profiles. The features of the flow and heat transfer characteristics for different values of the
Prandtl number are analyzed and discussed. Comparisons with previous work by other
method show good agreement.
