“…Yao et al [8,9] analyzed the mechanism of flow reduction through the detailed study of velocity cloud map and vector diagram, summarized the change law of velocity field, and further studied the flow reduction effect of S-type runner under different tip speed ratios. Ji et al [10][11][12] proposed a system of porous floating breakwaters with different distances. The research results show that the double-row floating breakwater system has better performance than the single-row floating breakwater system in many aspects.…”

Aiming at the breeding environment where the construction of marine pastures requires low wind and waves, a floating breakwater (FB) with a Savonius type (referred to as S type) runner with wave absorption and energy reduction function is studied for wave absorption and energy reduction in aquaculture sea areas. The wave-absorbing and energy-reducing performance of the floating breakwater is studied by the method of combining numerical simulation and experiment. Using Star-CCM+ numerical simulation software, based on linear wave theory and energy conservation law, using overlapping grid technology, calling DFBI model, second-order time discretization, a three-dimensional flow field model of the floating breakwater was established and numerically simulated. At the same time, a floating breakwater physical test system was developed for experimental verification, the transmission wave and the conversion power consumption of the S-shaped runner under different wave heights and different periods were measured, and the results Please carefully check the accuracy of names and affiliations. of numerical simulation and physical experiments were comprehensively evaluated. The research results show that the floating breakwater based on the S-shaped runner has the functions of reducing the wave height and reducing the wave energy, which have guiding significance for practical engineering.

“…Their results show that hydrodynamic performance is primarily affected by the wave conditions and immersion depth. The work of Ji et al (2018) and Cho (2016) shows that unique design characteristics such as porosity and deep side plates may also be significant as they reduce the influence of hydrodynamic loads. Recently, rectangular floating breakwater (RFB) and trapezoidal floating breakwater (TFB) have been broadly studied by some researchers (e.g.…”

This paper presents a two-dimensional simulation model for the idealisation of moored rectangular and trapezoidal floating breakwaters (FB) motions in regular and irregular waves. Fast-Fictitious Domain and Volume of Fluid methods are coupled to track-free surface effects and predict FB motions. Hydrodynamic performance is assessed by a machine learning method based on Cuckoo Search-Least Square Support Vector Machine model (CS-LSSVM). Results confirm that a suitable combination of the aspect ratio of an FB and her sidewall mooring angle could help attenuate incoming waves to a minimum height. It is concluded that moored trapezoidal FBs are more efficient than traditional rectangular designs and subject to further validation CS-LSSVM can be useful in terms of optimising the values of predicted wave transmission coefficients.
