摘要
采用多步Runge-Kutta与有限差分相结合的格式,离散叶轮机械内三维欧拉方程,应用代数法生成了压气机转子三维网格。用此方法模拟了NASA Rotor37跨音速压气机转子流场,计算得到的流场与试验结果进行了对比。结果表明,该方法收敛速度快,实用可行,计算简单省时。并且,该方法为研究叶轮机械内部流场计算提供了很好的基础。在此基础上进行更深层次的研究会变得很容易。
The three-dimensional Euler equations were solved by using Multistage Runge -Kutta schem and Finite Difference, structural grid generated with Algebraic Method. The internal flow field of the NASA Lewis Rotor37 was analysed using the numerical method. The results are compared with experimental data,indicating that this method has both the efficiency and practiealbility. In addition, the text offered a basic method to compute the internal flow fieht of turbomachinery. And it becomes easer to develop profound study.
