中文摘要:
这篇论文扩大放射应力的常规概念(Longuet-Higgins 和斯图尔特, 1964 ) 在进步的水里向站的波浪招手,以便它的垂直侧面能以一个新技术方法被定义并且计算。水动力学被结合的数字模型在承受波浪的垂直地变化的放射压力被用来模仿被在垂直的节承受波浪导致的水流。推迟的沉积运输的数字建模然后被执行模仿水流由好沉积组成的床的进化。模仿的 scour 和免职模式在对优先的实验室和地观察的质的同意。
英文摘要:
This paper extends the conventional concept of radiation stress (Longuet-Higgins and Stewart, 1964) in progressive water waves to standing waves, so that its vertical profile could be defined and calculated in a new technical way. The hydrodynamic numerical model being coupled with the vertically varying radiation stress in standing waves is used to simulate the currents being induced by standing waves in the vertical section. Numerical modeling of suspended sediment transport is then carried out to simulate the evolution of the bed composed of fine sediments by the currents. The scour and deposition patterns simulated are in qualitative agreement with prior laboratory and field observations.
