振动壁面对液滴碰撞动态行为的影响研究
Study on the influence of vibrating wall on the dynamic behavior of droplet impact
摘要
Abstract
The phenomenon of droplets hitting the vibrating wall widely exists in industrial production and nature,and the vibration phase of the wall affects the velocity and acceleration state of the wall,which in turn affects the dynamic characteristics of the impact droplets.Therefore,it is of great significance to determine the influence of different vibration phases on the dynamic behavior of droplets hitting the vibrating wall.The process of droplets hitting the vibrating wall of different collision initial phases was observed through high-speed camera experiments,and the influence of the initial phase of collision on the spreading and oscillation characteristics of the droplets after hitting the vibrating wall under different vibrational conditions was analyzed.The results show that the initial phase of the collision determines the relative position and motion trend of the wall,and the spreading time of the droplets increases first and then decreases with the increase of the initial phase of the collision.The maximum spreading factor decreases first and then increases with the increase of the initial phase of the collision.According to the force analysis and study of the oscillation characteristic curve of the droplet oscillation process,it is found that the value of the maximum central height of the initial phase of the 90° collision is the largest,and the initial phase of the droplet collision has little influence on the stability time of the droplet.When the amplitude of the wall vibration increases,the change of the droplet spreading characteristics and oscillation characteristics with the initial collision phase is basically unchanged.The trend of droplet spreading characteristics and oscillation characteristics with the initial collision phase is mainly frequency-related.关键词
