| 摘 要： | 用PDA对活塞顶具有ω型燃烧室的缸内二维紊流场进行了测量,讨论了气门偏置、燃烧室偏心、挤流以及活塞运动速度对平均速度和紊流强度的影响,结果表明:在进气过程中缸内气流是翻滚式的流动,而在压缩过程中则是朝向燃烧室的汇合流动.

| Abstract: | The measuring results of a two-dimensional turbulent flow field inside a cylinder with an co-type chamber on the piston top by PDA are reported. The effects of the offset valve, offset chamber, squish and piston velocity on the mean velocity and turbulence intensity are discussed. Test results show that the flow inside the cylinder is a tumbling one during intake and a confluent one toward the combustion chamber during compression. |
