文摘

Reveal conjugated convective heat transfer behaviors of impinging jet inside concave cavity. Effects of chevron-excitation on conjugate convective heat transfer. Optimum p/d is about 0.2 and l/d is about 0.1. Effect of chevron-excitation behave more significant under smaller jet Reynolds number. Effect of H/d behave little influence on the specific area-averaged heating effectiveness.
