| 摘 要： | 本文根据航天飞机防热瓦缝隙流动的特点,从二维定常不可压缩层流的 N-S方程出发,提出了一个简化流动模型,即缝隙的二维流动可近似当作两个准一维沟槽流动的线性迭加,由此给出了缝隙中的热流率与压力、压力梯度和缝隙宽度的变化规律,并利用现有的实验结果作了验证。

| Abstract: | A simplified gap flow model is deduced from N-S equa-tions for the 2-D steady incompressible laminar flow through tile gapson the space shuttle i.e:the 2-D gap flow can be approximatelytreated as the linear combination of two separate quasi-one-dimensionalchannel flows,The relationship between the gap heating rate, pressure:pressure gradient,and gap width is given.The influences of(?)andthe gap width on the gap heating rates are consistent with the avail-able experimental results. |
