单液滴撞击球形表面的涂覆效果
Coating and the Impact of Single Droplet on the Spherical Surface
摘要
Abstract
Droplet-spherical surface collision is a fundamental issue in the application of spray coating. Under the experi-mental conditions of different impact velocity(0.88-4.43,m/s)and different outer diameters of the spherical surface(5-15,mm),the impact of a single droplet on a spherical surface at room temperature was investigated by analyzing the changes of coating with the help of a high-speed camera. When contacting the spherical surface,the droplet spreads,retracts,relaxes or splashes on the surface. Consequently,the relationship between the K value,sphere diameter and impacting phenomena was established for theoretic analysis and numerical simulation.关键词
