摘要
针对海浪运动产生的巨大波浪能,设计一种Savonius桨叶与双浮筒式防波堤组合的波浪能转换模型。为了研究该新型防波堤的捕能性能和消波性能,对模型结构参数优化设计,基于试验数据进行插值拟合获得模型的最佳入水深度,再对模型在不同入射波波高和不同波浪周期条件下进行组合测试,对测得的捕获功率、透射系数等数据进行分析。基于黏性流体理论,利用STAR-CCM+软件进行数值模拟,并与物理试验结果进行对比验证。结果表明,该模型的捕能性能处于最佳区间时,消波性能最佳,说明该模型成功地进行了波浪能的捕获和转化,模拟值与试验值的差异较小,变化趋势基本一致。
Aiming at the huge wave energy generated by wave motion,we design a wave energy conversion model composed of Savonius rotor and a double-buoy floating breakwater.In order to study the energy capturing and wave elimination performance of the new type of breakwater,we optimize the parameters of the model structure,obtain the optimal water penetration depth of the model by data interpolation on the basis of the experimental data,then test the model under different incident wave heights and different wave periods,analyze the measured capture power coefficient,transmission coefficient and other data,apply the STAR-CCM+software for numerical simulation on the basis of the theory of viscous fluids,and compare with the physical experiment results for verification.The results show that the model has the best wave elimination performance when the energy capture performance of the model is in the best range,which means that the model successfully captures and transforms wave energy.The variation trend of the simulated data is basically consistent with the experimental data,and the differences of data are within the error allowable range.
