摘要/Abstract

摘要： 基于k-ε湍流模型，在STAR-CCM+平台上建立数值波浪水池，开发透水式多层开孔板消波装置并研究其消波特性.波浪水池利用流体体积(Volume of Fluid, VOF)方法追踪自由液面，采用STAR-CCM+的VOF WAVE模块造波，出口边界设置阻尼消波区.通过对一系列指定波浪的模拟，验证了数值水池的准确性.改变波长、波高、水流的流速和方向，可得到消波装置在不同波流条件下的反射与透射系数.结果表明：反射系数和透射系数均随波长增加而增大；反射系数随波高增加而增大，透射系数随波高增加而减小；波流共同作用工况下，反射系数和透射系数远小于波浪单独作用工况；在模拟波流条件下，所开发的消波装置消波性能显著.

关键词: 消波装置；波浪要素；反射与透射；波流作用

Abstract: Based on the k-ε turbulence model, a numerical wave flume was established to develop a pervious wave-absorbing device with multiple porous plates using CFD software STAR-CCM+. The volume of fluid (VOF) method was used to track the free surface and the wave was generated with the module of VOF WAVE with the wave-damping zone placed at the end of the flume. The results of regular waves verify the numerical method compared with the analytic solutions. The reflection and transmission coefficients of the wave absorbing device change with different wavelengths, wave heights and water-current conditions. The results showed that these coefficients increase with the increasing wavelength. The reflection coefficient increases and the transmission coefficient decreases with the increasing wave height. The reflection and transmission coefficients have a marked decrease because of the wave-current interaction. A conclusion is drawn that the wave-absorbing device has good wave-absorbing performance.

Key words: wave absorbing device; wave factors; reflection and transmission; wave-current interaction
