CENTRIFUGAL PUMP, characteristic curve

Hi my frineds,

I am simulating a centrifugal pump in CFX ANSYS 12, but I don't know how obtein the characteristic curve Q vs H.

Regards

Ivan :)

you mean the P-Q curve? i also do the centrifugal fan,you can contact with me use the msn:lihui54312@hotmail.com ,we can dissucs the detail

Have a look in the best practises guide int he documentation. There is one for pumps.

Q vs H = Capacity (GPM) vs Head (feet or meter)

My e-mail is tristan_rips19@hotmail.com

I simulated the impeller of centrifugal pump, with next information:

Inlet: 5.214 m/s
Outlet: 80000 Pa

But I don't obtain the characteristic curve.

Thanks

Ivan:)

At the BC of the simulation, u have to define the inlet volume flow rate of the pump. And the head can be calculated from the pressure drop of the pump, divided by ρg. H=(Poutlet-Pinlet)/ρg.
