In turbomachinery applications, we routinely take into account the effect of surface roughness, which (1) numerically affects the turbulence equation and (2) physically affects the flow separation prediction.
But I can imagine how this is ignored by the vast majority for general applications.

能简要介绍一下不同的观点大概都是什么吗?
我知道的就是大多数人拿着理论外形就开始画完格,不会考虑表面粗糙度,更不会管固壁与水的亲和力问题。 |
