| 1. | 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
对于冲击-逆向对流-气膜复合冷却的火焰筒结构而言,火焰筒壁面冷气侧的冲击冷却实质上是半封闭通道的冲击冷却,即冲击射流从冲击孔板喷出,冲击到换热靶面后形成壁面射流沿通道单方向流出。 |
