摘要
Huh-Scriven佯谬表明在连续介质假设下,若固体壁面指定无滑移边界条件将导致移动接触线处速度不连续和力学奇异性.以移动接触线力学奇异性及其消除机制为主线,从微观角度探讨了移动接触线的多尺度特性,综述了湿润过程中动态接触角的数理模型,讨论了仿真过程中针对移动接触线速度的几个处理方法.
Abstract
The Huh-Scriven paradox shows that under the continuum assumption,if the solid wall is specified with no slip boundary condition,the velocity at the moving contact line will be indescribable and the mechanical singula-rity will be caused.Based on the mechanical singularity of the moving contact line and its elimination mechanism,the multi-scale characteristics of the moving contact line are discussed from the microscopic point of view.The mathematical model of the dynamic contact angle in the wetting process is summarized,and several processing meth-ods for the velocity of the moving contact line in the simulation process are also discussed.
