ABSTRACT CTS-9408939 University of Hawaii Manoa P.I.: Kwok Cheung This project uses numerical and theoretical techniques to study the hydrodynamic response of a fluid membrane to gravity waves in order to understand fluid-membrane interaction. Fluid-filed membranes have various environmental applications, including use in breakwaters and temporary storage of contaminated water during site remediation or at times of flooding. In the modeling, and emphasis will be placed on solving problems related to large scale floating membrane systems. The static equilibrium configuration of the fluid filed membrane will first be calculated accounting for both large deformations and wrinkling of the membrane. The response of the filled membrane to waves will then be studied by a dynamic analysis that couples the finite element model with a boundary element technique. Available experimental results will be used to compare with simulations.

摘要 CTS-9408939 夏威夷大学马诺阿分校 项目负责人：Kwok Cheung 该项目使用数值和理论技术来研究流体膜对重力波的流体动力响应，以了解流体膜相互作用。 流体膜具有多种环境应用，包括在防波堤中使用以及在现场修复或洪水期间临时储存受污染的水。 在建模中，重点将放在解决与大型浮膜系统相关的问题。 首先将考虑膜的大变形和起皱来计算流体膜的静态平衡配置。 然后，将通过将有限元模型与边界元技术相结合的动态分析来研究填充膜对波浪的响应。 可用的实验结果将用于与模拟进行比较。
