【摘要】 随着新型燃烧方式的发展,喷雾撞壁现象广泛存在于现代内燃机的燃烧过程中。研究喷雾撞壁机理对提高内燃机热效率,降低污染物排放具有重要的意义。分别从实验和模拟研究出发,阐述了从基础喷雾液滴撞壁到实际发动机喷雾撞壁的研究现状,指出了现有喷雾撞壁研究存在的不足,为进一步开展燃油撞壁的研究提供参考。更多还原

【Abstract】 With the development of new combustion mode, the spray wall-impingement exists widely in combustion process of modern internal combustion engine. Studying the mechanism of spray wall-impingement is beneficial to improve the thermal efficiency and reduce the pollutant emissions. In this paper, the wall-impingement research status of the droplet and spray has been shown from experiments and numerical simulations, respectively. The disadvantages of the existing research are pointed out, and a reference for further research on spray wall-impingement is provided.更多还原
