摘　　要：喷雾液滴撞壁现象广泛存在于受限空间燃烧室中,研究喷雾液滴撞壁机理对提高燃烧效率,降低污染物排放有十分重要的意义。从实验、数值和理论三方面综述了液滴撞壁研究现状及发展,对液滴撞壁运动形态变化、碰撞影响参数、碰撞特性规律、相界面追踪技术以及液滴最大铺展系数理论求解进行了全面的阐述。通过深入分析液滴撞壁研究现状,指出了液滴撞壁研究的发展方向。Spray droplet impact is widely exsited in confined space combustion chamber, exploring on the mechanism of spray droplet impact has a siginificant meaning of improving combustion efficiency and decreasing pollution emission. This papre reviews the develop- ment of droplet impact on a surface from experimental, numerical and theorical aspects and conclude the morphologic changes, impact factors, impact characteristics, phase interface tracking technology and theorical solution of droplet maximum spreading factor. According to deep analysis on the development of droplet impact on a surface, the research direction is proposed.
