摘要
基于理想气体在水平流管内的定常流动,本文讨论了可压缩流动的基本性质,并与理想流体做了对比,分析了气体的可压缩性可以忽略的条件.
The fundamental properties of the compressible flow are discussed based on the steady flow of ideal gas in a horizontal stream tube, and are compared with those of ideal fluids. The condition in which the compressibility of gases is ignorable that is also analyzed.
