Suppression or Enhancement of Wave Motion in Film Flows

摘要CTS-0138057 S。林，克拉克森大学提出了一个联合的实验和分析研究的抑制或增强的波动在薄膜流。 本研究共有五个目的，其中三个是实验部分，两个是分析部分。 实验目标是（1）看看是否可以实现PI理论预测的对不稳定性发生的抑制，（2）是否可以实现预测的波浪运动增强，以及（3）通过实验证明可以违反乡绅定理。 目的（4）将稳定性理论推广到多层体系;（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.
