【摘要】 海洋工程国家重点实验室深海实验水池消波装置采用弧形消波滩结构及落水槽装置。根据有关规范对该消波潍的波浪反射系数作了计算。结果表明,对于波陡比较大的波浪,反射系数较小,大多在0．05以下; 而对于波陡比较小的波浪,反射系数较大。为考察落水槽对长波能量的吸收,运用FLUENT进行了数值模拟。结果表明落水槽装置对减小长波反射是有效的。更多还原

【Abstract】 A reservoir and an arc type of wave-absorbing beach are used in the deepwater offshore basin of the State Key Laboratory of Ocean Engineering. In accordance with the Code, wave-reflecting coefficients are calculated. The results indicate that the reflection coefficients are small when the values of wave steepness are big, most of them being below 0.05. However, the reflection coefficient is big when wave steepness is small. In order to explore the effect of wave energy absorption on the beach and in the reservoir for long wave, commercial software FLUENT is adopted for the simulation. The results show that reservoir device is efficient to diminish the energy reflected into the tank.更多还原
