| 摘 要： | 借助Fluent软件，采用湍流模型对一种转子螺纹头数与定子螺纹头数不等的梯形迷宫螺旋泵的内部流场进行了数值模拟，并分析了内部流场的速度与压力的分布规律。结果表明，此模拟泵的增压效果明显，泵内螺旋区域流体处于紊流状态，沿螺旋区域壁面法向，流体的速度梯度和压力梯度较大，流体对壁面冲击较大。

| Abstract: | The flow field of a trapeziform labyrinth screw pump for which the thread number of the stator was twice that of the rotor has been simulated using the Computational Fluid Dynamics software Fluent.Analysis of the flow characteristics,including the velocity and pressure fields,showed that the fluid in the field of the stator is subject to significant disturbance,and that the velocity and pressure gradients vary markedly along the direction normal to the wall. |
