9906941SlinnThis work will use direct numerical simulation to examine the processes by which obliquely incident internal waves reflect from a sloping boundary, generate currents flowing along the slope, and interact with these currents. These processes are important in the production of mixing near boundaries and hence have an effect on the ocean that extends far beyond the immediate vicinity of the boundary. The details of boundary mixing are difficult to observe in the field and in the lab. Both monochromatic and polychromatic incident wave fields will be considered. Key questions to be investigated are the time-dependent behavior of the strong along-slope currents generated by waves near the critical frequency and the way in which the spatial distribution of regions of strong mixing evolves.

9906941 slinn这项工作将使用直接数值模拟来研究斜入射的内波从倾斜边界反射的过程，产生沿斜坡流动的电流，并与这些电流相互作用。这些过程在边界附近混合的产生中是重要的，因此对海洋的影响远远超出了边界的直接附近。边界混合的细节很难在现场和实验室中观察到。将考虑单色和多色入射波场。研究的关键问题是由临界频率附近的波浪产生的强沿坡流的时间依赖行为以及强混合区域的空间分布演变的方式。
