Ship water-air-bubble mixture flows represent a complex hydrodynamic phenomenon driven by the intense interaction between marine engineering structures and the surrounding fluid. This phenomenon involves the vigorous penetration and mixing of water and air phases, the entrainment and suction of multiscale bubbles, and the splashing of liquid droplets, all characterized by extensive spatiotemporal scales and influenced by a multitude of factors. It is particularly pronounced in the vicinity of full-scale structures, significantly impacting ship performance, including resistance, propulsion, maneuverability, noise generation, and the hydrodynamic behavior of offshore platforms. This presentation is divided into two main sections: mechanism exploration and numerical simulation techniques. In the mechanism exploration section, we provide a detailed account of the current scientific understanding of the mechanisms governing the generation and evolution of water-air-bubble mixture flow. This includes an analysis of the interactions among water, air, bubbles, and mist, as well as factors contributing to the formation of water-air-bubble mixture around marine structures. In the numerical simulation techniques section, we trace the evolution of algorithms from interface-based models (such as VOF, Level-set, LBM, MPS) to non-interface models (Euler-Lagrange, Euler-Euler), and discuss key technical challenges. We highlight the recent achievements of the CMHL research team in the field of ship water-air-bubble mixture flow, encompassing enhancements in numerical methods, improvements in computational efficiency, and practical engineering case studies. Finally, the future research directions for ship water-air-bubble flows are presented, which include improving multiphase flow models, implementing high-performance computing techniques, and adopting research methods that combine experiments and simulations. These directions will facilitate a deeper understanding and simulation of water-air-bubble mixture flow’s impact on ship performance, offering crucial support and innovation for the optimization and safety of marine engineering applications.
