Difference b/t rotating wall and rotating domain?

Here is a confusing thing in simulating a pump. In general a rotating domain and a stationary domain are adopted for a pump simulaiton in CFX. I did it like the way. In stead of using the roating domain, could it be possible that the rotating blades and hub are set up rotating wall? Are there any difference?
Thanks in advance for your help. |

If you are not sure of the difference, you could try and see what would happen.
In a rotating domain, the fluid is subject to centrifugal force and the flow could be steady state in the rotating frame. In a stationary domain, if you simulate the flow as transient with moving wall (and moving mesh), I assume you could get the same result. But, would the flow be steady state if you only set moving walls? Would the next position of the wall affect current flow field? |
