The decay of a two-dimensional solitary wave into three-dimensional waves in film flow along a vertical plate has been studied using a high-speed laser-induced fluorescence technique that allows high spatial and temporal resolution measurements of the thickness of wave liquid films. It has been shown that the three-dimensional wave packet resulting from the decay of a two-dimensional solitary wave has a strong perturbing effect on the falling film and leads to the formation of rivulets on its surface.

二维孤立波在垂直下落液膜上形成三维波的实验研究

已经使用高速激光诱导荧光技术研究了二维孤立波在沿垂直板的薄膜流中衰减为三维波的问题，该技术允许对波液膜的厚度进行高空间和时间分辨率测量。研究表明，二维孤立波衰减产生的三维波包对降膜有很强的扰动作用，导致其表面形成小溪。
