潮流能电站载体水动力响应分析

Hydrodynamic response performance analysis of tidal current energy power plant carrier

随着海洋能开发向深水的发展,潮流能的开发也有向更深海域发展的趋势.稳定可靠的水轮机载体,对水轮机正常工作及发挥其最大工作效率有着很大的影响.针对深水中水轮机浮式载体的水动力响应性能,基于三维势流理论,利用SESAM软件计算分析了2种不同载体的水动力性能,在对浮体运动性能影响较大的横摇、纵摇水动力响应方面,双体船的最大横摇角及最大纵摇角明显小于单体驳船.经对比分析得出,双体船形式载体在水动力性能方面更具优势.

With the development of the deep ocean energy exploration, tidal current energy also has a trend of developing towards deeper waters. A reliable turbine carder has a significant impact on the normal work and the maximal efficiency of the turbine. Focusing on the hydrodynamic response performance of floating carrier of the turbine in a deep water, this paper presents the calculation on the hydrodynamic performance of two different carriers using SESAM software, based on the three-dimensional potential flow theory. On the aspect of roll and pitch, which have important effect on the floating motion performance, the maximum roll angle and pitch angle of catamaran is obviously smaller than that of barge. Comparisons show that the catamaran form has more advantages in aspect of hydrodynamic performance.
