Numerical Simulation of Centrifugal Pump Flow Field Based on Unstructured Meshes

  • 摘要: 相对于传统的理论和实验方法,采用数值模拟的方法能够更快捷地获得离心泵的内部流场分布。研究了离心泵全流场数值求解的方法,构建了离心泵的几何模型并划分非结构网格,采用了CFX软件,通过求解雷诺平均N-S方程,对离心泵流场进行了数值模拟,计算得到了离心泵在不同工况下的扬程和效率。将计算值与实验值进行了对比,在设计工况点Q的条件下,扬程相对误差为2.8%,效率值相对误差为1.8%。因此,针对离心泵建立的基于非结构网格的离心泵全流场数值求解方法是可靠的,能够快速准确的对离心泵进行性能预测与分析。
