ABSTRACT

A numerical model was proposed to analyse the combined effect of the pneumatic breakwater and the submerged breakwater for improving the wave damping performance, in which the Reynolds Averaged Navier-Stokes equations combined with the Shear Stress Transport (SST) k-ω turbulence model were adopted to investigate the flow field. A series of existing experiments were applied to validate the numerical model of the pneumatic breakwater and the submerged breakwater. The results indicated that the joint breakwater could dramatically enhance the wave dissipation capacity when the aerial barrier was located behind the submerged breakwater, and the transmission coefficient of the joint breakwater to the long waves could be decreased by 35% compared with the submerged breakwater working alone in some cases.

摘要

提出了一种数值模型来分析气动防波堤和水下防波堤对提高波浪阻尼性能的综合影响，其中雷诺平均纳维-斯托克斯方程与剪切应力传递 (SST) k - ω相结合采用湍流模型研究流场。应用一系列现有实验来验证气动防波堤和淹没式防波堤的数值模型。结果表明，当空中屏障位于水下防波堤后方时，联合式防波堤可以显着提高消波能力，联合式防波堤对长波的传输系数比单独工作的水下式防波堤降低35%。在某些情况下。
