我们将润湿的分子动力学理论应用于液滴在固体表面上铺展过程中动态接触角的弛豫。已经获得了几种固液组合的实验数据，并使用该理论成功拟合。根据液体和固体的微观特征提取和解释物理参数。我们还表明，液滴扩散和强制润湿可以用相同的方程来描述。对分子动力学框架内获得的结果与传统流体动力学理论获得的结果进行了比较。
We apply the molecular kinetic theory of wetting to the relaxation of the dynamic contact angle during the spreading of liquid droplets on solid surfaces. Experimental data have been obtained for several solid-liquid combinations and are successfully fitted using the theory. Physical parameters are extracted and interpreted in terms of the microscopic characteristics of the liquid and the solid. We also show that droplet spreading and forced wetting can be described by the same equations. a comparison is made between the results obtained within the molecular-kinetic framework and those obtained with conventional hydrodynamic theory.
