本文介绍了用时间推进法计算跨声速透平级三元流场的方法.应用本方法研究了静叶径向安装角对于级的反动度的影响.发现静叶压力面向下倾10度对于改善反动度沿径向的分布,有明显的效果.为进一步改进透平级的设计,提供了理论依据和数值模拟的手段.
In this paper, the method of calculating the transonic three-stage turbulent flow field by using the time propulsion method is introduced.The influence of the static angle of the radial installation angle on the level reaction is studied by using this method.It is found that the static pressure of the stator is inclined downward by 10 degrees, The radial distribution of the reaction has a significant effect.To provide a theoretical basis and numerical simulation means to further improve the design of the turbine stage,
