| 1 | 圆弧型贯底式多孔介质防波堤防浪效果的解析研究显示文摘针对圆弧型贯底式多孔介质防波堤防浪效果研究,给出了防浪效果计算的解析方法.假定防波堤刚性垂直薄壁,空间固定,水深恒定.假想存在一个圆柱面,把流场划分为内外区域,在每个区域上将速度势用特征函数展开,然后在它们的公共边界上进行匹配.匹配的原则是公共边界上速度连续,压力连续,从而可得到关于未知系数的一组线性代数方程组,解出未知系数,即可求得流域中任意一点的速度势和波高.数值结果给出了不同入射波波长、不同波向入射及防波堤不同孔隙率、不同张角时防波堤周围波幅分布的等高线图.结果表明,圆弧型贯底式多孔介质防波堤的防浪效果与入射波特征和防波堤的孔隙率密切相关. | 程建生 缪国平 王景全 尤云祥 | 2008 | 哈尔滨工程大学学报2008，29，1： | 5 |
| 2 | Wave Diffraction on Arc-Shaped Floating Perforated Breakwaters显示文摘An analytical method is developed to study the sheltering effects on arc-shaped floating perforated breakwaters. In the process of analysis, the floating breakwater is assumed to be rigid, thin, vertical, and immovable and located in water with constant depth. The fluid domain is divided into two regions by imaginary interface. The velocity potential in each region is expanded by eigenfunction in the context of linear theory. By satisfying continuity of pressure and normal velocity across the imaginary fluid interface, a set of linear algebraic equations can be obtained to determine the unknown coefficients for eigenfunction expansions. The accuracy of the present model was verified by a comparison with existing results for the case of arc-shaped floating breakwater. Numerical results, in the form of contour maps of the non-dimensional wave amplitude around the breakwater and diffracted wave amplitude at typical sections, are presented for a range of wave and breakwater parameters. Results show that the sheltering effects on the arc-shaped floating perforated breakwater are closely related to the incident wavelength, the draft and the porosity of the breakwater. | 段金辉 程建生 王建平 王景全 | 2012 | China Ocean Engineering2012，26，2： | 5 |

| 6 | ANALYTICAL RESEARCH ON THE WAVE DIFFRACTION OF ARC-SHAPED FLOATING BREAKWATERS显示文摘An analytical method was developed to study the wave diffraction on arc-shaped floating breakwaters. The floating breakwater was assumed to be rigid, thin, vertical, immovable and located in water of constant depth. The fluid domain was divided into two regions by imaginary interface. The velocity potential in each region is expanded by eigenfunctions. By satisfying continuity of pressure and normal velocity across the imaginary fluid interface, a set of linear algebraic equations could be obtained to determine the unknown coefficients for eigenfunctions. The accuracy of present model and the computer program were verified by a comparison with existing results for the case of arc-shaped bottom-mounted breakwaters. Numerical results, in the form of contour maps of the non-dimension wave amplitude around the breakwater, were presented for a range of wave and breakwater parameters. Results show the wave diffraction on the arc-shaped floating breakwater is related to the incident wavelength and the draft of the breakwater. | MIAO Guo-ping CHENG Jian-sheng WANG Jing-quan YOU Yun-xiang | 2006 | Journal of Hydrodynamics2006，18，1： | 1 |

| 8 | A review on liquid sloshing hydrodynamics显示文摘Liquid sloshing in tanks is a very complex nonlinear free surface fluid flow problem,which must be considered in most of the marine engineering problems such as naval architecture,offshore engineering and so on.Violent liquid sloshing in large containers can damage the tank structure due to the direct liquid impacting action.Sloshing also affects the capsizing process of the liquid cargo ship.Some works on mitigating sloshing by using all kinds of the baffles were thus followed with interests.Oil layers with thinner thickness were shown to reduce the sloshing load of water in tanks.The sloshing characteristics in tanks with different sizes were different,therefore,scaling effect of sloshing should also be considered.Sloshing in a tank can also be used as tuned liquid dampers(TLDs)to dampen wind,wave and flow-induced motions of floating or fixed marine platforms.This paper present an overview on recent advances of liquid sloshing hydrodynamics including sloshing mitigation by using anti-sloshing baffle,layered fluids sloshing,scaling effect of sloshing and TLDs. | Jin-hai Zheng Mi-An Xue Peng Dou Yu-meng He | 2021 | Journal of Hydrodynamics2021，33，6： | 0 |
| 9 | 新型DBA隔板结构下LNG储罐液体晃荡的数值研究显示文摘液舱晃荡是LNG(Liquefied Natural Gas)船设计中需要考虑的关键因素之一,晃荡现象除了会影响船舶的稳定性之外,还会损坏船体结构。为了能够有效地抑制液舱的晃荡,本文提出一种新型的DBA(Different Baffle Angle)隔板结构,重点考虑最危险载液率条件下,液舱发生晃荡共振时,不同转角及尺寸DBA隔板的制荡效果。通过对比晃荡波幅极值、壁面压强曲线、流场速度幅值以及液体的流动状态,甄选出最优隔板的结构形式。研究发现,DBA隔板会导致液舱的固有频率发生突变,诱导产生的涡旋可以有效地消耗激励频率附近的能量,当翼缘隔板与底部隔板长度相等且转角为60°时,DBA隔板制荡的效果最佳。 | 张茴栋 李琪 史宏达 | 2023 | 船舶力学2023，27，10： | 0 |
