摘要

摘要: 液滴的动态湿润现象广泛存在于自然界和工业生产中，该现象数值研究的建模需要解决接触线附近的奇异性并引入合理的接触角描述.基于相场方法，结合Yokoi动态接触角模型，建立了考虑动态润湿效应的两相流数值模型，并在OpenFOAM开源平台上实现相应程序.针对液滴撞击壁面的动态湿润过程，数值模拟和对比研究了不同的接触角模型.结果表明：接触角模型的选择对液滴动态润湿过程的模拟结果具有较大的影响，其中基于改进动态接触角模型的结果与文献中的实验结果具有很好的吻合度，反映了提出的数值模型在液滴的动态润湿行为模拟的有效性.

Abstract: Dynamic wetting phenomena of droplets are widely observed in nature and industrial production, the numerical research of which needs a solution of singularity and a correct model of the dynamic contact angle. Based on the phase field method (PFM) and the modified dynamic contact angle model, a 2-phase flow numerical method with dynamic wetting effects was developed, and the related program was realized on the OpenFOAM platform. The dynamic process of droplets impacting on a wall was simulated, and the comparison of the computation results of different contact angle models was conducted. The results indicate that the contact angle model influences the dynamic wetting process simulation significantly; the results of the proposed method are in good agreement with those of the experiment, which shows the proposed method is effective in the simulation of dynamic wetting phenomena.
