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。本文着重介绍传热系数的测量结果
In the Ludwieg wind tunnel, the authors studied the film cooling characteristics of the double row of cross-hatch holes. For the first time in the transient wind tunnel, the heat transfer measurements along both the mainstream and the transverse directions were achieved. Heat transfer coefficient changes in detail. This article focuses on the measurement of heat transfer coefficient
