Hello,

I am new to flow simulation and got really thrown into it and now I have to deal with it. I need to simulate a centrifugal pump. I know there is a lot of information already but also very different each time.

I want to get the characteristics curve of this pump-> set a flow rate and get head or the other way around, i dont know whats better.

 

My rotating region encloses my impeller and rotates with 2900rpm.

 

How do I need to setup my inlet and outlet the correct way? for example: i want to get the pressure difference at a flow rate of 0.005 m^3/s. or should i ask: what flow rate do I have with a head of 12 meters? I just dont know which is better and how to do it.

 

I use the sliding mesh approach.

 

I would thank you so much, if anyone could help me. I am really in trouble.
