Abstract
Numerical simulations are performed to systematically investigate the effect of the downstream crescent-shaped block height on the flow field and cooling performance for a configuration with a single row of an infinite number of inclined cylindrical holes at various coolant-to-mainstream blowing ratios. The numerical results show that placing a downstream block can significantly alter the downstream flow field due to generation of an additional anti-kidney vortex pair, which improves the cooling performance. Optimal block heights are determined for various blowing ratios.
