| 摘 要： | 利用CFD软件STAR—CD及ES—ICE对柴油机压缩喷雾过程进行数值模拟分析。模拟计算从进气过程开始，充分考虑了进气过程给缸内流场带来的影响，分析了喷雾前缸内流场及喷雾过程。研究表明，哑铃型燃烧室明显增强了压缩末期缸内涡流强度，燃烧室偏心布置使得缸内气流运动不均匀，燃烧室内的燃油分布也不均匀，各个喷孔方向上燃油喷射状况并不相同。

| Abstract: | The CFD software STAR-CD and ES-ICE was used to simulate the compress and injection process of diesel engine.The simulation started from the intake process,so the effects of intake process were fully considered,and analysis was focused on in-cylinder flow field before and after injection process.Research shows that dumbbell combustion chamber can obviously increase the intensity of swirl in cylinder,and the combustion chamber located eccentrically can make in-cylinder flow asymmetry,so was the distribution ... |
