摘要
当两种不同方向的风生成的波浪或涌浪传播到某一海区时,会出现大范围的方形波浪现象,对过往船舶的6自由度运动有很大的影响。论文基于CFD方法研究方形波浪中S175型船的运动。并基于动量源项和强迫波力技术建立了方形波浪的数值造波与消波方法。然后,基于重叠网格和VOF技术建立方形波浪中船舶运动的预报方法。分析了不同方形波浪参数对船舶运动性能的影响,为船舶遭遇方形波浪时的安全航行提供建议。
Phenomenon of cross sea occurs when wind or swell waves coming from two orthogonal directions approach to the same sea area.Ship motions induced by cross wave may be quite large and its navigational safety should be concerned.This paper investigates the motion behavior of a S175 hull advancing in cross waves with CFD method.Momentum source term and wave forcing techniques are used for generation and absorption of cross waves.Then ship motion prediction method is established by overset grid and volume of fluid(VOF)techniques.Influence of wave parameters on the ship motion is analyzed,which provides useful guidance for the safety of ship navigation when subject to cross waves.
