Two different radii of curvature and one row of vertical injection holes are considered. The Navier−Stokes equations are solved using a fine nonuniform multiblock staggered curvilinear grid and the SIMPLE-based finite volume method. The blowing rates are 0.5 and 1.0 and the mainstream Reynolds number is 10,000. The obtained results indicated that at a low blowing ratio, the cooling effectiveness enhances over the convex surface and reduces over the concave surface compared to the flat surface case. In comparison with the low blowing ratio, the curvature effects at a high blowing ratio seem to be less pronounced. At the high blowing ratio, the effectiveness is not greatly influenced by the surface curvature.
