| 摘 要： | 建立液滴在具有润湿梯度表面上运动的物理和数学模型,用Fluent软件模拟出液滴在润湿梯度表面上的运动过程,并从能量变化的方法得到液滴在润湿梯度表面上运动的机制.计算结果表明润湿性梯度表面上的液滴具有不同的能量状态,当液滴的接触角较大时,液滴的表面能较大,此时液滴可以自发地向低接触角的方向运动,润湿性梯度的分布状况将决定液滴运动过程的速度和加速度的大小.

| Abstract: | A physical and mathematical model of a droplet moving on a gradient wetting surface was established.The movement of the droplet on the gradient wetting surface was simulated by Fluent software.The theoretical basis of the movement of the droplet on a gradient wetting surface was obtained by the energy analysis.The results show that the wettability gradient on the surface of droplets has different energy state,when the droplet contact angle is larger,the droplet has larger surface energy,and this droplet can... |
