摘要
利用ANSYS-FLUENT流体仿真软件,建立了二维数值水槽模型,探究了多层平板透流防波堤对规则波的消浪效果。模拟了不同波浪周期、不同波高和不同板间距条件下防波堤消浪性能,得到了最优结构参数方案;综合考虑上述三种影响因素,拟合得到了多层平板防波堤透射系数计算公式。结果表明,透射系数最小值对应的最优相对板宽在0.35~0.45倍的波长之间,且相对板间距越大,消浪效果越好;该类防波堤对大波高波况的消浪效果较好,相对波高越大,透射系数越小。拟合出的透射系数计算公式与模拟结果较为吻合,可为多层平板透流防波堤的设计和应用提供参考。
A 2D numerical model of wave tank was built by using ANSYS-FLUENT fluid simulation software to evaluate the wave attenuation performance of multi-layer perforated plate breakwater subject to regular waves.By simulating the wave attenuation performance of the breakwater under the conditions of different wave periods,wave heights,and plate spacings,the optimum configuration of structure parameters were obtained.By fully analyzing the above three factors,a fitting formula was derived for calculating the transmission coefficient of the multi-layer perforated plate breakwater.The research results showed that the minimum transmission coefficient was achieved when the relative plate width ranged between 0.35 and 0.45 times the wave length,the increased relative plate spacing enhanced the wave attenuation effect,the above breakwater was of better wave attenuation performance under high wave condition,higher relative wave heights led to smaller transmission coefficient,the fitting formula accorded with the simulation data.The above may provide a reference for the design and application of multi-layer perforated plate breakwater.
