我们在这里描述旋转的液滴,并首先对可能的不同形状进行分类。然后,我们研究了液体弹珠的行为,它是包裹着疏水颗粒的液滴,沿着斜坡流下来。因为这些弹珠在运动的时候会滚动,所以这个装置可以让我们实现旋转滴。我们报告了在下降过程中产生的不同形式,并通过缩放参数量化它们的大小。我们最后将重点放在可能发生在不同水滴形状之间的转换上。
We describe here liquid drops in rotation, and first classify the different shapes possible. Then, we study the behaviour of liquid marbles, which are droplets coated with hydrophobic grains, running down inclines. Because these marbles roll as they move, this device allows us to achieve revolving drops. We report the different forms generated during the descent, and quantify their size by way of scaling arguments. We finally focus on the transformations which may occur between different drop shapes.
