    Analysis of Centrifugal pump

    Abbas Madraswala

      Hi,

       

      I want to perform CFD analysis of centrifugal pump to find the performance of pump. I have the actual tested data for this pump.

      I have define the internal volume flow rate at inlet and environent pressure at outlet.

      Applied real wall conditions on internal faces of casing.

      Local rotating region with 2900 RPM.

      In goals I have defined surface goal as:

      static pressure at inlet and outlet

      Volume flow rate at inlet and outlet

      torque on impeller

       

      Most of the time I got an error "Solver Abnormally terminted" after going more than 800 iterations.

      If it got solved, I observed that volume flow rate at inlet and outlet were not equal. They had a huge difference in value.

      The pressure difference and torque value were also very very high.

       

      Kindly suggest and help me out what changes I should make in the set up to achive the required results.

       

      Thanks in advance.

       

      Regards,

      Abbas
