99-10883苏格兰在这个项目中,PI将研究波浪边界层(WBL)内的沉积物输送。我们将用N-S方程的数值解来研究由海底表面重力波引起的振荡流所产生的边界层的动力学。平底和波纹底部都将被考虑(后者用于模拟沙纹)。对于小到中等的雷诺数,将直接求解方程,而对于较大的雷诺数,将使用大涡模拟方法。
英文摘要
99-10883ScottiIn this project, the PIs will investigate the transport of sediments within the wave boundary layer (WBL). A numerical solution to the Navier-Stokes equations will be applied to the dynamics of the WBL generated by oscillating currents induced by surface gravity waves over the bottom. Both flat and corrugated bottoms will be considered (the latter to simulate sand ripples). For small to intermediate Reynolds number, the equations will be solved directly, while for larger Reynolds numbers, a Large Eddy Simulation approach will be used.
