Hello,

 

I am looking to generate a pump curve for a submerged pump with a free liquid surface.

Can someone please point me to some tutorials or other instructions that would be helpful in doing this?

Are you modelling all of the pump inards too? 

[Terry Price]

yes I am.

And you're expecting to get air in the pump? If so you'll have a fun model and need VOF, although you may be OK with Mixture/Eulerian depending on whether you need to worry about the quality of the free surface.

Well, actually I lied, it's not a submurged pump but a pump with a liquid level like in the picture shown below.  It was easier to explain it as a submerged pump as a liquid level than try to explain the picture below.  But now I drew the picture at anyrate...

 

so, there's a liquid level inside the pump, and I was wondering the best way to model it.

VOF if you expect the level to vary. To avoid the need to work out all of the hydrostatic boundary conditions use the Open Channel options available via VOF.
