摘要

波浪能转换器(WECs)是用来提取波浪能的。然而，这种装置在商业应用上仍然很昂贵。为了通过与防波堤共同分担建设成本来降低微气泡水防波堤的成本，提出了一种集成的圆柱形微气泡水防波堤系统，该系统在超长防波堤前设置一个圆柱形微气泡水阵，以提取波浪能量并衰减入射波。本文的目的是对整体圆柱形wect型防波堤系统的性能进行优化。使用了计算流体动力学工具OpenFOAM®和基于势流理论的求解器HAMS®。OpenFOAM®为改进版的HAMS®提供粘度校正，以便准确有效地预测集成系统的性能。对集成系统进行了参数化优化研究，并发现了一种带有额外圆弧结构的新型设置，可以显着提高集成系统的性能。

Optimisation of the Hydrodynamic Performance of a wave energy converter in an Integrated Cylindrical WEC-Type Breakwater System

Wave energy converters (WECs) are built to extract wave energy. However, this kind of device is still expensive for commercial utilisation. To cut down the cost of WECs by sharing the construction cost with breakwaters, an integrated cylindrical WEC-type breakwater system that includes a cylindrical WEC array in front of a very long breakwater is proposed to extract wave energy and attenuate incident waves. This paper aims to optimise the performance of the integrated cylindrical WEC-type breakwater system. A computational fluid dynamics tool, OpenFOAM®, and a potential flow theory-based solver, HAMS®, are utilised. OpenFOAM® provides viscosity corrections to a modified version of HAMS® in order to accurately and efficiently predict the integrated system's performance. Parametric studies are conducted to optimise the integrated system, and a novel setup with an extra arc structure is found to significantly improve the performance of the integrated system.

期刊介绍： The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events. Scope: Offshore Mechanics, Drilling Technology, Fixed and Floating Production Systems; Ocean Engineering, Hydrodynamics, and Ship Motions; Ocean Climate Statistics, Storms, Extremes, and Hurricanes; Structural Mechanics; Safety, Reliability, Risk Assessment, and Uncertainty Quantification; Riser Mechanics, Cable and Mooring Dynamics, Pipeline and Subsea Technology; Materials Engineering, Fatigue, Fracture, Welding Technology, Non-destructive Testing, Inspection Technologies, Corrosion Protection and Control; Fluid-structure Interaction, Computational Fluid Dynamics, Flow and Vortex-Induced Vibrations; Marine and Offshore Geotechnics, Soil Mechanics, Soil-pipeline Interaction; Ocean Renewable Energy; Ocean Space Utilization and Aquaculture Engineering; Petroleum Technology; Polar and Arctic Science and Technology, Ice Mechanics, Arctic Drilling and Exploration, Arctic Structures, Ice-structure and Ship Interaction, Permafrost Engineering, Arctic and Thermal Design.
