Based on the secondary development in Fluent,the study built a 2D numerical wave tank by the method of momentum source. Firstly,the established wave tank was used to simulate the resonance phenomenon between the waves and multi-floating bodies,and the numerical results were in good agreement with the experimental data. The results showed that the horizontal force acting on the last body was the largest. Subsequently,the influences of draft on resonance phenomenon were analyzed,indicating that the horizontal force acting on each body was,on the whole,correlated with its draft while the relation between vertical force and draft varied with the body. In the end,the influence of the addition of third body on resonance phenomenon in the gap was discussed,showing that resonance frequency would move to lower and the second resonance frequency would probably appear when the third body was added into the floating system.
