摘　　要：为深入探究卷破波破碎的动态过程,利用循环水槽,以及高速摄像设备,进行了卷破波破碎和船舶升沉量的相关试验.卷破波部分,详细描述了卷破波从波峰接近垂直开始,到最终波浪能量释放完毕的全过程.试验中,观察到卷舌形成至消散的全过程,包括波峰的变化、水团-气腔的形成及其在不同阶段的演化,直至波浪破碎完成.并使用高速摄像机,通过船舶升沉量试验的设计与研制船舶下沉量试验装置,在典型工况下测量了船模下沉量.分析结果表明,水团-气腔的尺寸随波浪状态显着变化,其最大值出现在卷舌与液面接触前的瞬间.靖江船舶升沉量的试验结果与数值计算结果进行了对比,证明了结果的可靠性.In order to deeply explore the dynamic process of wave breaking,the relevant tests of wave breaking and ship heave were carried out by using circulating water tank and high-speed camera equip-ment.In the part of wave breaking,the whole process of wave breaking from the peak near vertical to the final release of wave energy was described in detail.In the experiment,the whole process from the formation to the dissipation of the tongue curl was observed,including the change of peak,the forma-tion of water mass-air cavity and its evolution in different stages until the wave was broken.The high-speed camera was used to design and develop a ship sinking test device through the ship sinking test,and the ship model sinking was measured under typical working conditions.The analysis results show that the size of water mass-air cavity changes significantly with the wave state,and its maximum value appears at the moment before the tongue touches the liquid surface.The experimental results of ship heave in Jingjiang are compared with the numerical results,which proves the reliability of the results.
