【摘要】 通过对常用的流体动力学各种控制方程的适用范围和条件进行讨论,以fluent软件为工具,以螺旋离心泵为对象,利用fluent软件中提供的6种典型数值模型对其内部流动进行计算并分析对比,探讨了各模型计算螺旋离心泵内部流动的特点以及模型所反映的内部流动机理.更多还原

【Abstract】 Several generally used governing equations in fluid mechanics were discussed.The interior flow in screw centrifugal pump was computed,compared and analyzed by using six typical numerical models provided by software fluent.The flow feature in the pump and the mechanism of its inner flow given by these models was discussed.更多还原
