| 摘 要： | 建立了液滴撞击等温固体平壁的物理和数学模型,数值模拟了撞击后液滴的变形和反弹过程,将模拟结果与文献中的实验结果做了比较,两者吻合较好,表明所采用的模型可以模拟液滴在水平壁面上的运动形态.通过比较不同条件下铺展因素随时间的变化规律,分析了液滴碰撞速度、初始接触角对变形过程的影响.

| Abstract: | Physical and mathematical models are established to simulate a deforming and rebounding process after a droplet impacting on isothermal flat solid.The simulated results are compared with the experimental results in relative literature,and a good agreement is obtained.Therefore,the adapted model can be applied to simulate the droplet deforming morphological feature after impacting.By comparing the spreading factors at different conditions,the effects of impacting velocity and the initial contact angle on the... |
