| 摘 要： | 文章介绍跨音松弛法应用于叶栅绕流的定常与非定常流场计算。在定常流中,采用弦线法向小扰动假定;在非定常流中,采用线化非定常分量小扰动假定,从而简化了数值求解过程。由于松弛法大大地节省机时和内存,便于工程上推广应用。

| Abstract: | This paper presents an approach that transonic relaxation methodis applied to compution of the flow field around cascades on steady andunsteady flows.On steady flow small disturbance hypothesis in normality ofchord is assumed and on unsteady flow small disturbance hypothesis of line-arized unsteady component is assumed,so that the numerical solution proce-dure is simplified.Because the relaxation method saves computer time andmemory space,it is benefit of wide application in engineeing. |
