基于C-CUP方法和亚网格方法，采用动态SGS模型，发展了一种新的数值计算方法，用于求解复杂的气-水混合流动问题，并将其应用于含气泡和气溶胶的气-水界面。该模型不仅能模拟波浪破碎，而且能模拟破碎后复杂的湍流气水混合流动，并能正确考虑自由表面湍流、空气卷吸和飞溅等高度非线性运动。在此基础上，讨论了浪区溅起循环过程中气泡的湍流结构和物理作用。
A new numerical scheme based on the C-CUP method with a subgrid-scale approach using the Dynamic SGS model is developed to solve the complicated air-water mixing flow problems and is applied to the air-water interface with air bubbles and aerosol excited by wave breaking. The numerical model succeeds in simulating not only wave breaking but also the complicated turbulent air-water mixing flows after breaking, and is useful for the proper consideration of highly nonlinear motions including free-surface turbulence, air-entrainment, and splash-up cycles. On the basis of the present simulated results, the turbulent flow structures and a physical role of the entrained air bubbles during splash-up cycles in the surf-zone are discussed.
