Hydrodynamic Interaction and Coalescence of Two Fluid Drops

本研究采用解析与数值模拟相结合的方法，探讨液滴在运动过程中的紧密相互作用、变形与合并。需要解决的具体问题包括：近球形液滴的润滑力和流动性函数、碰撞率预测、中间膜排出时间以及范德华力的影响。开发一个适用于此类现象的模型并由此进行预测，将提高在沉淀、乳状液和絮凝领域的预测能力。

This research employs analytical and numerical modeling to explore the close interaction, deformation, and coalescence of liquid drops in motion. Specific issues to be addressed are: the lubrication force and mobility functions of nearly spherical drops, collision rate predictions, intervening film drainage times, and the influence of van der Waals forces. The development of a suitable model for such phenomena, and predictions from it, will lead to improved prediction capability in the areas of sedimentation, emulsions, and flocculation.
