摘　　要：本文建立了大气喷射器的三维计算模型,并利用ANSYS-Fluent软件进行了三维仿真模拟,所得结果与两台水环-大气喷射真空泵的现场数据具有可比性,表明所建模型的合理性,同时与轴对称模型的比较结果表明,三维仿真模拟考虑了结构和流场的非对称因素,所得结果更加合理.In this paper,a three-dimensional calculation model of the air ejector is established,and the three-dimensional simulation is carried out by using the software ANSYS-Fluent.The results obtained are compatible with the field data of the two water-ring air ejector pumps,which shows the rationality of the model.At the same time,the comparison with the axisymmetric model shows that the results are more reasonable as the three-dimensional simulation accommodates the asymmetry of structure and flow field.
