| 摘 要： | 利用FIRE软件建立了某柴油机螺旋进气道的三维仿真模型，对进气流动进行了CFD模拟计算。在用气道稳流试验台验证了仿真模型的准确性后，分析了进气道内部的流场分布。利用模型的方便性考察了进气门座圈倒角、进气道放置角度等结构参数对进气流场分布的影响，得到了一些有参考价值的结论。

| Abstract: | The three-dimensional simulation model of the spiral inlet duct of a diesel engine is created with the FIRE software,and CFD simulation of inlet flow is carried out.The accuracy of the simulation model is verified by inlet duct steady flowing pressure tests on test benches,and then flow field distribution in inlet ducts is analyzed.Influences of some structural parameters,such as inlet valve seat ring chamfer,inlet duct setting angle,on the inlet flow field distribution are investigated with the model.and several valuable conclusions are drown. |
