摘要
潮流水轮机是潮流能转换装置的核心装备,潮流水轮机水动力性能和载荷则是潮流能转换装置总体设计和结构设计的基本依据。到目前为止,流动分离、流固耦合、空化以及复杂环境条件等强非线性因素对潮流水轮机水动力的影响仍然是一个值得研究的问题。本文基于哈尔滨工程大学在潮流能利用技术领域多年的研究成果,对潮流水轮机在均匀流水动力分析和流固耦合分析的不同数值方法及相关计算结果进行了回顾和对比分析,并提出了一种水轮机波浪载荷的计算模型。
The tidal current turbine is kernel equipment of the tidal current energy conversion（TCEC） device,with its hydrodynamic performance and loads being the basis of the overall and structural design of the TCEC device. So far, the effects of some nonlinear factors, such as flow separation, fluid-structure interaction, vacuoles and complex environmental conditions, on the turbine hydrodynamic performance are still worth further research.Based on the academic achievements in the field of tidal current energy technology obtained by the Harbin Engineering University, review and comparative analysis are conducted on the numerical methods and corresponding results in uniform flow hydrodynamic analysis and fluid-structure interaction analysis of tidal current turbine. Finally, a numerical model is presented on the wave loads of turbines.
