液滴撞击移动及旋转表面过程研究综述

Review on droplets impact process on moving and rotating surfaces

基于现有液滴撞击移动及旋转表面的研究,简要阐述液滴撞击移动表面及旋转表面的现象;将移动表面分为平移固体表面、旋转固体表面和移动液膜3种形式,从实验系统、模型建立和数值模拟3个方向对现有的液滴撞击移动表面研究进行总结.液滴撞击移动及旋转表面的研究已有一定基础,而高撞击速度、微小液滴、旋转表面等情况的研究较为空白,旋转表面波推进等理论和实验结果也缺乏数值模拟的补充.基于上述情况,提出液滴撞击移动表面及旋转表面的研究展望.

Based on existing research on droplet impact on moving and rotating surfaces,the phenomenon of droplet impact on moving and rotating surfaces needs to be briefly summarized.Moving surfaces can be divided into three forms:translating solid surfaces,rotating solid surfaces,and moving liquid films.The comprehensive study and summary on the impact of liquid droplets on the moving surface from three directions:experimental system,model establishment and numerical simulation.The research on droplet impact movement and rotating surfaces has a certain foundation,while the research on high impact velocity,small droplets,rotating surfaces and other situations is relatively blank.The theoretical and experimental results of rotating surface wave propulsion also lack numerical simulation supplementation.Based on the above situation,the research prospects of droplet impact on moving and rotating surfaces are proposed.
