摘要：To investigate the interactions between the bidirectional regular wave trains, the numerical 'X' configurations with different approaching angles were designed based on a fully non-hydrostatic 3D free surface flow model. The interactions of two identical regular wave trains with a relatively approaching angle of 16 degrees were firstly simulated to verify the present model. Then, to have a deeper understanding of the influence of propagation direction on the interactions between the bidirectional wave trains, more numerical simulations with larger approaching angles were conducted. The results show that the approaching angle of wave trains is highly correlated with the interaction between bidirectional regular waves, large approaching angle can lead to intense interactions and strong three-dimensional characteristics of the wave trains after interaction. Furthermore, the maximum wave height produced by interaction was obviously observed to be reached before propagating to the center of the interaction region for large approaching angle.
