摘要

摘要浸没式圆形防波堤铺设在底部某一点，与刚性矩形防波堤相比，简化了其安装。在本研究中，进行了数值模拟，以评估圆形和矩形淹没式防波堤的传输系数，改变不同的水力/几何有效参数。进行了灵敏度分析，以评估不同波高、水深和底坡的各种参数对透射系数的有效性。使用两相自由表面流动模型进行了数值模拟。界面跟踪也使用改进的精细网格体积跟踪流体体积（FGVT-VOF）方法进行。通过实验测量对数值结果进行了验证，表明数值模型准确地预测了传输系数；因此，数值计算结果对淹没式防波堤的设计具有一定的指导意义。最后推导了圆形淹没式防波堤的透射系数的计算公式。

A study on the performance of circular and rectangular submerged breakwaters using nun-uniform FGVT method

ABSTRACT Submerged circular breakwaters are laid to a point at the bottom, simplifying their installation compared to the rigid rectangular ones. In the present study, numerical simulations were performed to evaluate the circular and rectangular submerged breakwaters transmission coefficient, changing different hydraulic/geometric effective parameters. A sensitivity analysis was performed to evaluate the effectiveness of various parameters on the transmission coefficient for different wave heights, water depths, and bed slopes. Numerical simulations were performed using a two-phase free surface flow model. Interface tracking was also performed using the modified fine grid volume tracking-volume of fluid (FGVT-VOF) method. Experimental measurements were employed to verify the numerical results, suggesting that the numerical model accurately predicts the transmission coefficient; thereby, the numerical results are useful for designing submerged breakwaters. An equation was finally derived to determine the transmission coefficient of the circular submerged breakwaters.

期刊介绍： Coastal Engineering Journal is a peer-reviewed medium for the publication of research achievements and engineering practices in the fields of coastal, harbor and offshore engineering. The CEJ editors welcome original papers and comprehensive reviews on waves and currents, sediment motion and morphodynamics, as well as on structures and facilities. Reports on conceptual developments and predictive methods of environmental processes are also published. Topics also include hard and soft technologies related to coastal zone development, shore protection, and prevention or mitigation of coastal disasters. The journal is intended to cover not only fundamental studies on analytical models, numerical computation and laboratory experiments, but also results of field measurements and case studies of real projects.
