研究了两个固定的樟脑圆盘与水面接触时的同步运动。当两个樟脑圆盘之间的距离大于8 mm时，圆盘底部的水面形状独立振荡。而当距离小于7 mm时，则出现同步振荡。根据距离的不同，马兰戈尼对流的性质和弯月面形状的差异发生了变化。对流是基于Navier-Stokes方程进行数值模拟。同步的机制进行了讨论的Marangoni对流的滚动结构。
The synchronized motion of the water surfaces in contact with two fixed camphor disks was investigated. When the distance between the two camphor disks was greater than 8mm, the shapes of the water surfaces at the bottoms of the disks oscillated independently. In contrast, synchronized oscillation was observed when the distance was shorter than 7mm. Depending on the distance, the nature of the Marangoni convection and the difference in the shape of the meniscus changed. The convection was numerically simulated based on the Navier–Stokes equation. The mechanism of synchronization is discussed in relation to the rolling structure of the Marangoni convection.
