| Abstract: |
| Breaking wave is a complex physical phenomenon that takes place at the gas-fluid interface, which is the chief reason for the generation of two-phase turbulence, wave energy dissipation, and mass transfer between air and water. For marine hydrodynamics, the breaking bow wave of high speed vessels induces the bubble-mixed flow travelling around the ship, eventually developing to be the turbulent wake which is easy to be detected by photoelectric equipment. Besides, the flow-induced noise stemming from wave plunging may weaken the acoustic stealth of water surface craft. In the oceanographic physics context, wave breaking accounts for the energy and mass exchange of the ocean-atmosphere system, which has a great effect on the weather forecasts and global climate predictions. Due to multi-scale properties of multiphase turbulent flows, a wide range of time and length scales should be resolved, making it rather complicated for experimental and numerical investigations. In early reviews[1-4], general mechanisms related to wave breaking problems are well-described. However, previous emphasis lies on the phenomenological characteristics of breaking wave. Thus, this review summarizes the recent experimental and numerical advances of the studies of air entrainment, bubble distribution, energy dissipation, capillary effect, and so on. |

| 波浪破碎实验和数值研究进展 刘成，胡一丁，李政，万德成 （上海交通大学 海洋工程国家重点实验室，船舶海洋与建筑工程学院，高新船舶与深海开发装备协同创新中心，上海 200240） 摘要： 波浪破碎是发生在水气界面处一种复杂的物理现象，是两相湍流产生、波能耗散以及水气之间质量传递的主要原因。对于船舶水动力学，船舶航行产生的船首破波会引起气泡混合流，最终演化为易被光电设备探测到的湍流尾迹。此外，由波浪破碎引起的流激噪声可能会影响声纳探测设备正常工作，减弱船舶隐身性能。在海洋物理学中，波浪破碎是海洋-大气环流能量和物质交换的重要原因，对天气预报和全球气候预测有重大影响。由于多相湍流的多尺度特性，使得对于波浪破碎实验和数值研究相当复杂。在早期综述中，充分描述了与波浪破碎问题相关的一般机理。然而，以前的研究主要关注波浪破碎的现象特征。本文综述了近年来研究波浪破碎中空气夹带、气泡分布、能量耗散和毛细管效应等方面的实验和数值研究进展。 关键词：波浪破碎；能量耗散；空气夹带和空隙率；气泡和液滴分布；毛细效应 |
