@东岳 感谢东岳老师的回答。
我参考了相关文献,low-Mach-number assumption 应该是忽略了压力波动,使得密度、焓等变量与压力波动无关。
那是不是意味着问题还是属于可压缩的呢?论文里面提到:
With these assumptions, the compressible energy equation is greatly simplified so that the resulting low-Machnumber equations are represented in tensorial notations as follows:
然后就是上面的三个控制方程。
那上面有关DNS的问题老师了解吗?
谢谢!
