【摘要】 为了给新型开敞式混流泵的设计奠定基础,对开敞式混流泵的内部流动进行了整机数值模拟,介绍了流场分析和性能预测的方法,给出了各过流部件的内流场和外特性曲线,通过外特性的计算结果与模型试验数据的比较,验证了计算的可靠性。在基本模型的分析基础上,改变混流泵的开敞式出水机构,进行轴向有导叶、轴向无导叶和径向无导叶等三种不同结构形式的内部流动模拟和外部性能预测,对结果进行比较分析,为有关工程应用打下基础。更多还原

【Abstract】 To make the base of design of the new open mixed flow pump, steady fluid field are simulated by CFD software under multi-work conditions of mixed flow pump, and the numerical methods are introduced. Interior flow characteristics and exterior performance of mixed flow pump are analyzed roundly, and the results show that the numerical results agree well with the experimental results. Based on the original model analysis, interior flow characteristics and exterior performance of mixed flow pump with three different discharge structures are calculated, and analyze the Head and efficiency of each structure under static and total pressure respectively. It establish the engineering application of the open mixed flow pump.更多还原
