Jet impingement cooling is an advantage method in heat transfer enhancement owing to its extremely high local heat transfer coefficient and simple structure. as regard as the combustor flame tube cooling structure is concerned, the impingement - converse convection - film composite cooling is an effective method, in this composite cooling structure, the impingement cooling problem could be modeled as impingement inside semi - confined channel
對于沖擊-逆向對流-氣膜復合冷卻的火焰筒結構而言，火焰筒壁面冷氣側的沖擊冷卻實質上是半封閉通道的沖擊冷卻，即沖擊射流從沖擊孔板噴出，沖擊到換熱靶面后形成壁面射流沿通道單方向流出。Furthermore, the horseshoe shape vortex system occurred to the upstream of the jet exit and the layer structure of vortexes occurred to the wake of the reverse flow region downstream of the jet are also investigated
