奇怪的现象-搅拌器负压

文章分类:cfd流体力学  发布时间:2024-07-11

最近因为想了解搅拌器的有效作用范围,查阅了很多资料

搅拌器和水泵类似,流量和转速一次方成正比,扬程和转速的二次方成正比,对于水泵来说,如果要实现高扬程,需要进行多级叶轮的设置

对于搅拌器,如果在一个很深的水中,下意识我们会认为在距离搅拌器很远的地方不会对水体造成影响

为了确定这个距离,做了很多个流态分析,但是发现总是有负压产生

无论是稳态的MRF 或者瞬态的华裔网格,得出的速度流场图都差不多如上所示

很是奇怪,这个问题留起来等后续研究。

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
