奇怪的现象-搅拌器负压-2

文章分类:cfd流体力学  发布时间:2024-07-12

之前仿真搅拌器出现了负压,今天做了测试,换一个搅拌器的形式看是不是还会出现同样的情况

这个搅拌器是完全3d扫描的版本,不存在模型的问题

网格质量也没有问题,对于叶轮部分进行了细化,整体网格质量在0.1以上 扭曲率小于0.8

利用滑移网格进行仿真,结果还是在搅拌器后出现明显的真空区!

分析压力:


可以看到搅拌器后有一大块负压区。

通过预览网格运动,也可得运动方向没有问题


到底是为什么,等待进一步分析。

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.
