RESEARCH PROGRESS IN HYDRODYNAMICS OF WIND-WAVE COMBINED POWER GENERATION SYSTEM

  • 摘要: 随着化石能源枯竭和全球变暖等环境问题的日益严重,海洋可再生能源(海上风能、波浪能和潮流能)成为研究热点. 为了有效开发海洋可再生能源,降低成本,多种能源综合开发成为现阶段的趋势. 海上风能与波浪能结合具有广阔的应用前景,联合发电系统不断创新. 水动力性能是联合发电系统与波浪相互作用的重要基础. 本文简要介绍多种应用在联合发电系统上的水动力学数值模拟方法,包括线性频域、线性时域、势流非线性方法标识码基于 Navier-Stokes 方程的黏性方法,对现有文献的水动力学数值模拟方法进行综述,从计算效率和精度标识码析其优缺点,且进一步阐述水动力控制优化的技术原理与实验技术主要科研难点,为联合发电系统的水动力设计提供依据. 得到以下主要结论:从计算效率上看,线性频域方法最优,其次为线性时域、势流非线性、黏性方法,从计算精标识码,与前者恰好相反;综合考虑计算效率和精度,采用考虑黏性修正的势流方法来研究是一个切实可行的方案;模标识码方法和优化控制技术目前还不够成熟,尚处于探索阶段.

     

    Abstract: With the increasing environmental problems such as depletion of fossil energy and global warming, marine renewable energy (offshore wind energy, tidal energy and wave energy) has become a research hotspot. In order to effectively develop marine renewable energy and reduce costs, comprehensive development of multiple energy sources has become a trend at this stage. The combination of offshore wind energy and wave energy has broad application prospects, and the combined power generation system continues to innovate. Hydrodynamic performance is an important basis for the interaction of combined system with waves. This paper introduces briefly a variety of hydrodynamic numerical simulation methods for combined power generation systems, including linear frequency domain, linear time domain, potential flow nonlinear method, and viscous method based on Navier-Stokes equation. The numerical simulation method is reviewed, and its advantages and disadvantages are analyzed from the aspects of computational efficiency and precision. The technical principle and main research difficulties of hydrodynamic control optimization and experiments are further elaborated, which provides a basis for the hydrodynamic design of the combined power generation system. The main conclusions are as follows. Firstly, from the perspective of computational efficiency, the linear frequency domain method is optimal, followed by linear time domain, potential flow nonlinearity, and viscous method. From the perspective of computational accuracy, it is the opposite of the former. Secondly, considering the computational efficiency and precision, it is a feasible solution to study the potential flow theory considering viscosity correction. Thirdly, at present, model experiment method and optimal control technology are not mature and still in the exploratory stage.
