SGER: A Numerical Study of the Effects of Bottom Topography on a Free Surface

本研究计划为期一年，旨在探讨地形诱导湍流撞击自由表面的物理现象，并探讨 在各种情况下的海底地形的表面检测。 的 PI将使用自由表面对以下流动进行大涡模拟（LES）： 四种情况：1）单一多项式山，2）二维正弦 地形，3）三维正弦地形，以及4）通道，以及 浅滩形态 将对数值输出进行分析， 表面上的应力和平流模式，可用于识别 底层地形

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.
