对由垂直板的脉冲水平运动产生的移动接触线周围的流场进行了数值研究。求解了二维非定常纳维-斯托克斯方程以及自由表面上的运动学和动态边界条件。发现自由表面与垂直板之间的接触角非常接近于以相同恒定加速度运动的矩形罐中所含流体的自由表面所形成的接触角。由此，基于质量守恒定律，得出移动接触线的速度作为板加速度的函数。
The flow field around a moving contact line, generated by an impulsive, horizontal motion of a vertical plate, is studied numerically. The two‐dimensional, unsteady Navier‐Stokes equations, coupled with the kinematic and dynamic boundary conditions on the free surface, are solved. The contact angle between the free surface and the vertical plate is found to be very close to that formed by the free surface of a fluid contained in a rectangular tank that moves with the same constant acceleration. The velocity of the moving contact line is thereby derived as a function of the acceleration of the plate based on the principle of mass conservation.
