摘要
运用CFD软件STAR-CD对某拖拉机用柴油机螺旋进气道进行了三维数值模拟。通过模拟计算可以比较准确地得到直观的进气道和缸内流场。模拟计算的涡流比及流量系数与试验结果具有较好的一致性,并对偏差产生原因进行了分析。
The three-dimensional flow field in a diesel engine helical intake port was numerically simulated using STAR-CD, and the 3D flow field was obtained. The evaluations, swirl ratio and flow coefficient, obtained from the simulation were validated on the steady flow test rig. And the causes of the evaluation offsets were analyzed.
