项目摘要
The project is for a one year study to explore the physics of topographically- induced turbulence impinging on a free-surface, and to explore the feasibility of surface detection of bottom topography in a variety of circumstances. The PI will perform a Large-Eddy Simulations (LES) with a free-surface for flows in four scenarios: 1) a single polynomial hill, 2) two-dimensional sinusoidal topography, 3) three-dimensional sinusoidal topography, and 4) a channel and shoal configuration. The numerical output will be analyzed to investigate patterns of stress and advection on the surface which may be used to identify underlying topography.
本计划为期一年,目的是探讨由地形引起的湍流撞击自由表面的物理现象,并探讨在各种情况下对海底地形进行表面探测的可行性。PI将在四种情况下使用自由表面进行大涡模拟(LES): 1)单个多项式山丘,2)二维正弦地形,3)三维正弦地形,以及4)通道和浅滩配置。数值输出将被分析,以研究地表的应力和平流模式,这些模式可用于识别下伏地形。
