The effects caused by these vortices distort the hydrodynamic and thermal boundary layer profiles, and they may modify the heat transfer rates. Results of a numerical investigation of the effects of Goertler vortices on heat transfer enhancement from a boundary layer flow over walls of variable curvature are reported. Fully concave, concave-flat and concave-convex configurations are considered. The results provide evidence that one may effectively decrease heat transfer rates of a transitional flow by changing curvature.
