The film-cooling adiabatic effectiveness was investigated by the heat-transfer experimental method with different pitch between inlet holes of the slot film. 摘要通過(guò)傳熱試驗法對不同縫槽進(jìn)氣孔間距的純氣膜冷卻效率進(jìn)行研究。
And the spanwise cooling effectiveness is improved significantly when the distance between the two small coolant jets is longer and the blowing ratio is higher. 在各吹風(fēng)比條件下，氣膜孔下游有射流小孔時(shí)，冷卻效率都有一定的提高，并且射流小孔間距較大時(shí)對兩氣膜孔中心線(xiàn)之間的橫向平均冷卻效率改善較大，吹風(fēng)比較大時(shí)，效果更明顯。
