Centrifugal pump's Test performance prediction from CFD

  1. Jan 22, 2010 #1
    How can we predict the actual test performance of pump from CFD. I need some formulation/calculation method to predict closure.

    There are lots of tools developed for just this. Typically our approach for compressors is to start with a meanline or 1D code first. Basically it's a glorified "velocity-triangle" approach to solving, but will get you very close.

    From there a model is created and meshed. For the best mesh quality, we bring it into ANSYS ICEM in order to get a full hex mesh. Mesh quality if very important with CFD; always.

    At that point it's brought into your solver and solved. Moving boundaries can be applied to the rotor and from what I've seen, results can be quite close to experimental values.

    And then we put it in the test cell and tell Minger that he's out to lunch :tongue2:
