| 摘 要： | 气液两相流动与固壁相互作用的研究是液滴撞击壁面运动研究的重要基础.以结合了VOF和Level Set两种方法优点的用于气液相界面追踪的复合Level Set-VOF方法和利用唯象分析方法建立的能够反映接触角滞后性及壁面性质对润湿过程影响的壁面润湿模型为基础,提出了气液两相流动与固壁相互作用耦合求解流程,给出了气液两相流动与固壁相互作用耦合求解过程中接触线速度的计算方法及边界条件的确定方法.通过与已有实验结果的对比,对提出的气液两相流动与固壁相互作用耦合求解方法的有效性进行了验证.

| Abstract: | The study of the coactions of gas-liquid two-phase flows with walls is an important base for the study of the process of a droplet impinging onto a wall.Based on the combined Level Set-VOF method that integrates the advantages of VOF method and Level Set methods and the wall wetting model that can reflect the influences of the contact angle hysteresis and the properties of the wall surface,the coupled solution flow chart for the coactions of gas-liquid two-phase flow with walls was put forward,and the calculation method of the contact line speed and the boundary conditions in the process of coupled solution for the coactions of gas-liquid two-phase flows with walls was presented.The method of coupled solution for the coactions of gas-liquid two-phase flows with walls were validated by the comparison of the calculation results with the experimental results. |
