摘      要：To obtain the interaction characteristics between Internal solitary waves(ISWs)and submerged bodies,a three-dimensional numerical model for simulating ISWs was established in the present study based on the RANS *** velocity entrance method was adopted to generate the ***,the reliability of this numerical model was validated by comparing it with theoretical and literature ***,the influence of environmental and navigation parameters on interactions between ISWs and a fixed SUBOFF-submerged body was *** to research,the hydrodynamic performance of the submerged body has been significantly impacted by the ISWs when the body is nearing the central region of the ***,the pitching moment(y )will predominate when the body encounters the ISWs at a certain angle between 0°and 180°,and the lateral force is larger than the horizontal ***,the magnitude of the force acting on the body is mostly affected by the wave *** variation of the vertical force is the main way that ISWs affect the hydrodynamic performance of the *** investigations and findings discussed above can serve as a guide to forecast how ISWs will interact with submerged bodies.
