Curvature effects on heat transfer in the free jet boundary

The Coanda effect, which is known to exist in flows associated with velocity discontinuities around airfoils, may include the effects of high temperature and thermal radiation. A physical interpretation of the steady, two-dimensional incompressible flowfield for such cases, and the boundary conditions which apply, are presented. It is found that the radiative boundary layer displays a sensitivity to curvature that grows more pronounced as Reynolds number value increases. Attention is given to flow behavior for the cases of the predominance of conduction and of radiation.
