    Centrifugal pump

    Aibolat Dyuisenakhmetov

      Dear All,

      I need your help. At university, we were doing flow simulation of a pump that is used by SolidWorks as validation for the simulation of rotation (SolidWorks Flow Simulation 2013 - Technical Reference). The BC are flowrate at inlet and environmental pressure at outlet. We wanted to calculate its efficiency. We need answer for some questions:

      1) Which parameters do we need to choose to calculate pressure drop?

      2) Which parameter should we use as a convergence criterion?

      3) Why the value of torque do not converge?

      Thank you in advance,

      Aibolat

          have you checked the forum? lots of good discussions about this recently

           

          1) goals at inlet and outlet for static pressure > equation goal for drop/change

          2) inlet/outlet mass flow is a good first step

          3) would need more information, likely mesh is too coarse or bad selections, or your setup is bad

           

          I would recommend you contact your reseller through your educator to see if they will provide you some technical support and/or training. If that doesn't work, make sure to go through ALL of the tutorials, tech references and solving engineering problems and the solidworks kb.

              Dear Jared Conway,

              Thank you for the answer. Could you please clarify what you mean by saying that setup is bad? Because I think the mesh is fine enough.

              Also should not we use total pressure at inlet and outlet to calculate pressure drop for the efficiency? Honestly, I do not find SW tutorials on flow simulation very useful but we went through some tutorials like ball valve, centrifugal pump etc.

              Regards,
