摘要
作者在 Ludwieg风洞中研究了双排叉排孔的气膜冷却特性 ,首次在瞬态风洞中实现了沿主流方向和横向两个方向的传热测量 ,并给出了近孔区壁温和传热系数的变化细节。
The film cooling performance downstream of injection from two staggered rows of holes were investigated in a Ludwieg tube wind tunnel.For the first time,heat transfer measurements were conducted in both streamwise and spanwise directions in a short duration flow facility.The details of wall temperature and heat transfer coefficient in region close to injection holes have been were obtained.
