【摘要】：波浪漫灘是近岸波浪的小尺度運(yùn)動(dòng),在實(shí)際海域的波生流數(shù)值計(jì)算中通常被忽略。本文基于Boussinesq方程的FUNWAVE模式,分別采用波浪漫灘邊界、固壁邊界、海綿邊界進(jìn)行Haller波浪港池物理模型實(shí)驗(yàn)的數(shù)值模擬,比較三種邊界計(jì)算結(jié)果與實(shí)驗(yàn)觀測數(shù)據(jù)的誤差,檢驗(yàn)波浪漫灘邊界對(duì)波生流數(shù)值計(jì)算的影響;然后設(shè)計(jì)了多種周期、波高的波生流數(shù)值模擬試驗(yàn),分析多種波浪入射條件下波浪漫灘邊界對(duì)近岸波生流數(shù)值計(jì)算的影響。結(jié)果表明,波浪漫灘對(duì)鄰近區(qū)域波生流有明顯影響,漫灘邊界下的波生流計(jì)算結(jié)果更接近實(shí)驗(yàn)觀測值,在近岸波生流數(shù)值模型中引入波浪漫灘邊界可以提高波生流計(jì)算精度。
[Abstract]:Wave floodplain is a small scale motion of near-shore waves, which is usually neglected in the numerical calculation of wave-induced currents in the real sea area. In this paper, based on the FUNWAVE model of Boussinesq equation, the numerical simulation of the physical model experiment of the Haller wave harbor is carried out by using the wave flood boundary, the fixed wall boundary and the sponge boundary, respectively, and the errors between the three boundary calculation results and the experimental observation data are compared. The influence of wave overbank boundary on the numerical calculation of wave-induced current is tested, and the numerical simulation experiment of wave generated current with various periods and heights is designed to analyze the influence of wave overbank boundary on the numerical calculation of wave-generated current in the near shore under various wave incidence conditions. The results show that the wave floodplain has obvious influence on the wave-generated current in the adjacent region, and the calculation results of the wave-induced current at the floodplain boundary are closer to the experimental observation value. The accuracy of the wave-induced current calculation can be improved by introducing the wave-surfacing boundary into the numerical model of the near-shore wave-generated current.
