Most hydrodynamic problems in ship and ocean engineering are complex and highly coupled. Under the trend of intelligent and digital design for ships and ocean engineering structures, comprehensive performance evaluation and optimization are of vital importance during design. In this process, various coupling effects need to be accurately predicted. With the significant progress of computational fluid dynamics (CFD), many advanced numerical models were proposed to simulate the complex coupling hydrodynamic problems in ship and ocean engineering field. In this paper, five key coupling hydrodynamic problems are introduced, which are hull-propeller-rudder coupling, wave-floating structure coupling, aerodynamic-hydrodynamic coupling, fluid structure coupling and fluid-noise coupling, respectively. The paper focuses on the numerical simulation techniques corresponding to each coupling problem, including the theories and the applications. Future directions and conclusions are provided finally.
