injectant

1.The inclined between injectant and mainstream is 35° and the hole spacing is 3 times film hole diameter.

结果表明：当速度比小时，射流在被保护壁面上铺散控制；

2.An investigation was conducted to explore the influence of density ratio and velocity ratio of mainstream/injectant upon the cooling effect of flat plane film using heat-mass transfer analogy.

采用传热传质类比方法研究主射流密度差和速度比对单排平板气膜冷却效率影响。
