摘　　要：为了探究液滴在金属基微结构表面的微润湿机理,借鉴仿生荷叶表面的乳状凸起,设计了一种乳突微柱结构.对乳突微柱上处于Cassie态的液滴进行理论分析,并利用多项流VOF模型的仿真方法,研究了乳突微柱结构的几何参数对接触角的影响.In order to explore the micro-wetting mechanism of droplets on the surface of metal-based microstructures,a mastoid microcolumn structure is designed by referring to the milky protrusion on the surface of the bionic lotus leaf.Through theoretical analysis of the Cassie droplet on the mastoid microcolumn and the simulation method of multiple flow VOF model,the influence of the geometrical parameters of the mastoid microcolumn on the docking antenna was studied.
