燃油粘度与环境压力对喷雾碰撞过程的影响(Investigation of the Influences of Droplet Viscosity and Environmental Pressure on the Spray Collision)
内燃机 喷雾模拟 碰撞模型
2010/12/28
O’Rourke碰撞模型仅仅考虑了碰撞拉伸分离以及聚合,而忽略了碰撞反弹、反射分离以及高韦伯数下的碰撞二次破碎过程,在碰撞分区过程中也忽略了燃油物性以及碰撞环境条件的影响,使得预测的碰撞分区临界韦伯数偏低。复合碰撞模型根据相关的实验结果对碰撞分区进行油滴粘度以及碰撞环境压力修正,考虑碰撞反弹、反射分离、拉伸分离以及碰撞二次破碎过程,提高了碰撞分区的预测精度。基于复合碰撞模型,分析了油滴粘度与环境压...
