Model and Simulation on Flow and Pressure Characteristics of Axial Piston Pump for Seawater Desalination

Article Preview

Abstract:

With cavitation model being considered, a LP (Lumped Parameter) model and a CFD (Computational Fluid Dynamics) model on the flow and pressure characteristics of the axial piston pump for seawater desalination were created. Based on the geometry structure and operating condition of the pump, these two models were numerically calculated and corresponding results were compared and discussed. Both the two models can describe the dynamic flow and pressure characteristics of the pump. The CFD model is accurate and many details such as cavitation position can be predicted. LP model is a simplified model compared with CFD model. Because the damping effect of the inlet of the pump is neglected, this model is only suitable for rough calculation in engineering.
