摘要
本文对一般性的三维非定常流动,通常引入面迹的概念,将三维非定常流动(或定常流)转化为面迹上的二维非定常流动或三维定常流动问题。该理论为解三维非定常流或跨音流提供了一种可能的新途径,对叶轮机内较复杂的流动问题,可通过该理论来简化研究模型,使理论和实验研究得以简化。
Through the concept of traces of substantial surface (T. S. for short), problems of three-dimensional unsteady (or steady) flow are transformed into those of two-dimensional unsteady or three-dimensional steady flow. This theory provides a new approach to the solution of three-dimensional unsteady flow or steady transonic flow. According to this theory, flow models, which makes theoretical research easier and experimental research more convenient and economic, could be found to simplify complex flow problems in turbomachine.
