论文名称:Numerical modeling of droplet-substrate interaction Using Lattice Boltzmann Moment Model 论文类型:期刊论文 发表刊物:Computational Thermal Sciences 收录刊物:EI、Scopus 卷号:3 期号:3 页面范围:179-186 摘要:The shape and surface texture of a liquid droplet were studied in two dimensions when a droplet impinges on a solid substrate under isothermal conditions. The lattice Boltzmann moment model was applied to simulate the fluid dynamics considering the adhesive interaction between fluid particles and surfaces. The results show the influence of wetting on the process and the drop shape For a hydrophobic surface, the process after impinging may be divided into two stages: the spreading process driven by inertial forces and the subsequent oscillations (recoiling process) driven by surface tension forces; while for the hydrophilic surface, the droplet will only deposit on the surface and there is no recoiling stage. In addition, the effects of the impingement speed on the droplet shape and texture were studied. The spreading speed and the maximum droplet diameter increase with the rise of the impingement speed. The evaporation and thermal effects were underlined and illustrated. ? 2011 by Begell House, Inc. 发表时间:2011-01-01
