摘　　要：The interaction between ship and surrounding fluids generates the water-air-bubble mixed flow laden with numerous droplets and bubbles.The water-air-bubble mixed flow is a complex multi-phase flow phenomenon,which involves intense air-water mixture,complex evolution of interface shape,interactions between multi-scale flow structures and strong turbulent fluctuations.Based on the field observations at sea,a large range of white water-air-bubble flow exists widely around a large-scale sailing ship,and directly affects the hydrodynamic performance of ship from various aspects.This paper reviews the research progress of water-air-bubble mixed flow around a ship.Current knowledge about the formation and evolution mechanism are introduced firstly.Then,the effects of the water-air-bubble mixed flow on ship performance are further reviewed,the main concerns are ship resistance,propulsion performance,slamming and maneuverability.Finally,the future research prospects are summarized.
