摘要
本文介绍利用双脉冲激光全息术研究柴油机喷雾油束的宏观运动瞬时速度和喷雾粒子的微观运动速度.得到了节流轴针式油嘴喷雾油束在喷射开始1ms内宏观运动速度分布规律的新认识,并给出了喷雾粒子微观运动轨迹照片,讨论了喷雾粒子场的微观速度分布规律.
This paper presents some experimental results of the instantaneous macro-speed of diesel fuel spray and the micro-speed of droplets in a diesel fuel spray by using double pulse holographic technique. A new knowledge of macro-speed of diesel fuel spray for throttle pintle type nozzle within 1 ms after injection has been gotten. A photography showing the travelling track of diesel fuel spray droplets is given and the velocity distribution of droplets in a diesel fuel spray field is discussed.
