Suppression or Enhancement of Wave Motion in Film Flows

摘要CTS-0138057S。建议开展一项关于抑制或增强薄膜流动中波动运动的实验和分析相结合的研究。本研究共有五个目标，其中三个在实验部分，两个在分析部分。实验的目的是(1)看看是否能实现PI理论预测的抑制不稳定性的开始；(2)是否能如预测的那样实现波动的增强；(3)实验证明，斯奎尔定理是可以违反的。目的(4)将稳定性理论推广到多层系统，(5)研究波动的弱非线性效应。PI没有明确讨论拟议研究的更广泛影响，但每年将培训三名研究生。

AbstractCTS-0138057S. Lin, Clarkson UniversityIt is proposed to carry out a combined experimental and analytical investigation on the suppression or enhancement of wave motion in film flows. There are five objectives of this research, three are in the experimental part, and two in the analytical part. The experimental objectives are (1) to see if suppression of onset of instability as predicted theoretically by the PI can be achieved, (2) whether enhancement of wave motion can be realized as predicted, and (3) to demonstrate experimentally that the Squire's theorem can be violated. Objective (4) is to extend the stability theory to a multilayer system, and (5) to investigate the weakly nonlinear effects of the wave motion. Broader impacts of the proposed research was not discussed explicitly by the PI, but three graduate students will be trained per year.
