Wave breaking is one of the most violent phenomena in air-water interface interactions that need to be considered in ship and offshore structures design. Spilling breaking waves induced by a shallowly submerged hydrofoil are investigated using a Navier-Stokes solver for two-phase flow. Computed wave profiles and velocity fields are compared with experimental results and good agreement obtained. A related non-breaking wave case is designed based on the same numerical model to distinguish the hydrodynamic characteristics of the spilling breaking waves and allow investigation of effects on waves downstream. The velocity profile and turbulence intensity profiles at different sections from the two cases are compared with measurement data, where available. A detailed comparison of the wave-breaking process compared to the non-breaking wave is provided. Further, the energy dissipation processes for the two cases are analyzed and the ratio of the turbulent dissipation rate to the total energy dissipation calculated. It is shown that a large amount of energy is dissipated in the region of the breaking wave when compared to the non-breaking wave. Approximately 12% of the total energy dissipation may be attributed to the wave-breaking process, induced by energy redistribution and additional contributions to turbulent fluctuations in the breaker.

破波是空气与水界面相互作用中最猛烈的现象之一，在船舶和近海结构设计中需要加以考虑。使用Navier-Stokes求解器对两相流研究了由浅水淹没的水翼引起的溢流破裂波。将计算出的波剖面和速度场与实验结果进行比较，并获得了很好的一致性。基于相同的数值模型设计了一个相关的非破碎波工况，以区分溢出的破碎波的水动力特性，并允许研究其对下游波的影响。将两种情况下不同部分的速度剖面和湍流强度剖面与测量数据（如果有）进行比较。提供了与非破浪相比破浪过程的详细比较。此外，分析了两种情况下的能量耗散过程，并计算了湍流耗散率与总能量耗散之比。与非破坏波相比，在破坏波的区域中耗散了大量能量。总能量耗散的大约12％可能是由于能量重新分配以及对断路器中湍流波动的其他贡献而引起的波浪破碎过程。
