摘要
基于分析物理机理,本文提出了一种切实可行的研究波流场中水动力系数的理论方法,同时对振荡流动中所得水动力系数如何应用于实际的波动情况进行了探讨,并与实验结果进行了比较。结果表明,通过对纯波时的水动力系数和纯流时的水动力系数加权平均,可以获得令人满意的波流共存时的水动力系数。
Based on the analysis of physical mechanics, a theoretical method to determine the hydrodynamic coefficients in wave-current co-existing fields is proposed in this paper, and the method how to apply the results obtained from oscillatory flow experiments to wave motion is investigated as well.The results are compared with experimental data.It is shown that we can obtain the coefficients in wave-current fields by taking an weighted average over those in pure wave and pure current fieldsatisfactorilys.
