中文摘要：
利用数值计算和实验观察相结合的方法研究液滴与水平固体壁面碰撞后的铺展过程，讨论液滴在铺展的各个阶段的压力分布特性和速度分布特性。数值计算结果表明液滴与固体壁面的接触角、液滴半径大小、液滴黏度、冲击速度等因素对铺展过程中液滴的最大铺展半径和最大反弹高度有影响。数值结算结果与实验观察结果一致。
英文摘要：
The process that the drop impacts on the solid wall was inrestigated by numerical simulation and experimental observation. The whole process was divided into five stages where the pressure distribution and velocity distribution of the drop were studied. The numerical results, which show good agreement with the experimental results, indicate that the radius of the drop, viscosity, and impact velocity, as well as the contact angle, could affect the max radius of the spread and the max rebound height.
