Abstract

Convex curvature affects adversely on a boundary layer structure that in turn leads to a "suppression" of turbulence, decrease in a rate of heat transfer and surface friction. Effect of a surface curvature should be taken into consideration in precise prediction of heat transfer and skin friction.
This paper presents results of a numerical simulation of heat transfer and hydrodynamics over the convexly curved wall with and without pressure gradient. The gradientless flow correlations have been used as a reference correlations to establish effect of pressure gradient. The initial boundary layer thickness was equal to zero, the boundary layer development has been calculated on a base of a computer code containing a six-point finite-difference scheme.
