摘要
基于三维频域势流理论,以小间隙的旁靠双驳船系统为研究对象,计算其在波浪中运动的水动力参数以及驳船周围的波面升高。结果表明:小间隙对双驳船系统的水动力性能以及周围的波面升高影响显著;通过考虑不同间距,研究间距对双驳船系统水动力性能的影响,发现各水动力参数的峰值所在频率随间距的增大而减小,对应的波长与间距呈现一定的线性关系。通过对多浮体相互影响的规律与机理进行研究,为海洋工程实践中多浮体系统的研究、设计提供一定的参考。
The hydrodynamic performance of a two-barge system with a small gap in side-by-side configuration was studied using three-dimensional linearized potential-flow theory. The hydrodynamic parameters and wave elevations around barges were calculated and results show that the small gap has strong influences on them. Furthermore, different gap sizes were taken into account in numerical simulation and results show that for the hydrodynamic parameters, there is a significant trend that the wave frequency corresponding to the peak value decreases with the gap size. The research on the rules of the multi-body interaction can be used for design and further analyses of multi-body floating systems.
