摘要(Abstract):

为深入研究旋涡泵内部流体的流动机理,掌握叶轮叶片高度变化对旋涡泵性能的影响规律,通过实验测得一款闭式叶轮开式流道旋涡泵在不同叶轮叶片高度下的流量-扬程特性曲线,采用k-ε湍流模型和非结构网格对该旋涡泵进行数值模拟,通过ANSYS CFX后处理对其内部流场进行分析,研究了旋涡泵叶轮叶片高度变化对旋涡泵外特性的影响规律。结果表明:旋涡泵的模拟结果与实验数据趋势基本吻合,数值模拟方法的可靠性较高。在相同流量工况下,随着叶轮叶片高度的减小,旋涡泵内部的纵向旋涡强度逐渐减小,叶轮流道内的涡核心减少,导致旋涡泵的扬程与效率逐渐降低。研究结果可为后续旋涡泵的优化设计提供参考。
