| 摘 要： | 发展了基于拟压缩方法的求解叶轮机械低马赫数流场的方法,研制了时间推进方法对叶轮机械全流速范围流场的求解计算程序,且对拟压缩因子的取值进行了讨论.通过对离心压缩机叶片扩压器的数值计算表明,发展的基于拟压缩方法能够快速正确的预测叶轮机械内的低速流场;引入拟压缩方法是对时间推进方法的一个很好补充,使时间推进方法的应用范围得到了拓展.

| Abstract: | Owing to the type of the flow governing equation system,and the low efficiency of standard time-marching algorithm in solving the low Math number flows,a time marching code was explored to solve the incompressible internal flow field of turbomachinery based on the pseudo compressibility method.In the full paper,we explained our exploration in some detail;in this Abstract,we just added some pertinent remarks listing three topics of explanation.In the first topic,a universal N-S equation system was derived,wh... |
