摘要
建立了内燃机换气系统普遍使用的弯曲圆形管道气体流场计算的三维模型及有关边界条件．利用本模型编制了计算程序，对内燃机气道弯曲圆形管道的流场进行了模拟计算，同时分析了各结构参数对流场的影响．
The model of three-dimensional flow in circular bend tube which is widely used in gas exchange system of internal combustion engine is developed in this paper. Using this model,the program is drawn up, and the flow in circular bend tube of internal combustion engine is calculated. Meanwhile, the influence of parameters on the flow is analyzed.
