在强迫骚乱的单色频率的 flowrate 下面的周期的矩形的墙的表面上的掉落的电影的表面波浪动力学经由数字模拟被学习。在周期的矩形的墙上形成的波形与扁平的板上的那些不同。在低频率,首先在入口介绍的不安经历一个稳定的流动区域然后发展成独居的波浪。当频率变得更高时,独居的波浪消失。当这部电影下面旅行,在稳定的流动区域和独居的波浪的特征的电影变丑被学习。在依赖于本地电影特征和折皱的几何学的周期的墙的消沉有发行量。而且,折皱的流动率和几何学能也影响单色的不安的发展。
Surface wave dynamics of falling film on the surface of periodic rectangular wall under monochromatic- frequency flowrate forcing disturbances is studied via numerical simulation. Waveforms formed on the periodic rec- tangular wall are different from those on the flat plate. At low frequency, the perturbation introduced at the inlet first undergoes a steady flow region and then develops into solitary waves. When the frequency becomes higher, solitary waves disappear. Film deformations in the steady flow region and characteristics of solitary waves are studied as the film travels down. There are circulations at the depression of periodic wall which are dependent on the local film char- acteristics and geometry of the corrugation. Moreover, the flow rate and geometry of the corrugations can also affect the evolvement of the monochromatic perturbation.
