摘　　要：滑移边界条件表示固液界面处的速度不连续性.采用VOF(Volume of Fluid)方法捕捉两相相界面的移动,利用自适应笛卡尔网格技术提高了运动界面求解的精度和分辨率,实现了液滴撞击动力学的数值模拟.通过实验对比了液滴撞击光滑固体表面的运动特征,研究了固液界面边界滑移对液滴撞击亲水/疏水壁面引发振荡行为的影响.The slip boundary condition represents the velocity discontinuity at the solid-liquid interface.The VOF(volume of fluid)method is used to capture the movement of the two-phase interface,and the adaptive Cartesian grid technology is used to improve the accuracy and resolution of the solution of the moving interface.The numerical simulation of droplet impact dynamics is realized.The motion characteristics of droplets impacting a smooth solid surface are compared experimentally,and further the effect of boundary slip of solid-liquid interface on the oscillation behavior caused by the droplet impacting a hydrophilic/hydrophobic wall is studied.
