摘　　要：大型邮轮是一种大尺度、高附加值船型,近年来得到越来越多的研究与开发.由于大型邮轮经常航行于港口、沿岸等繁忙水域,研究其与其他船舶的水动力相互作用,对保证其航行安全至关重要.以一艘大型邮轮和一艘KCS集装箱船为研究对象,通过求解非定常RANS方程,在模型尺度下预报了两船在深水、浅水中不同纵向位置、不同横向位置以及不同航速下的水动力特性,确定了两船之间水动力相互作用的变化情况.结果表明,不同的相对位置和航速均对两船的横向力和转首力矩有明显影响,浅水下两船的相互作用更加明显,且KCS船更易受到船-船相互作用的影响.The large cruise ship is a type of ship with large size and high added value,which has been increasingly studied and developed during the recent years.Since a large cruise ship often sails in the crowded waters such as harbor and coastal area,the study of the hydrodynamic interaction between the cruise ship and other ships is crucial to ensure the navigation safety.Taking a large cruise ship and a KCS container ship as the study object,the hydrodynamic characteristics of the two ships at different longitudinal positions,transverse positions,and ship speeds in both deep and shallow water are predicted in model scale by solving the unsteady Reynolds-averaged Navier-Stokes(RANS)equations,and the variations of the hydrodynamic interactions between the two ships are identified.It is shown that different relative positions and ship speeds have significant effects on the lateral force and yaw moment acting on the two ships.The hydrodynamic interaction between the two ships in shallow water is more remarkable,and the relatively smaller ship is more affected by the ship-to-ship interaction.
