摘　　要：三体船构型复杂,主侧体间相互干扰影响因素较多。为了研究三体船船体周围流场细节与主侧体间的流场干扰,运用计算流体力学(CFD)软件STAR-CCM+对三体船和主船体进行了不同航速的数值模拟,提取船体周围与主侧体间的流场信息,获得不同速度下的兴波、横截面垂向速度和横截面矢量流线演化。研究三体船与单体船的流场差异特性,分析三体船中侧体对单独主船体流场的扰动,获得了三体船船体兴波与流场流线随航速变化的规律,为三体船的阻力性能和整体布局的优化提供参考。The configuration of a trimaran is complex,and there are many factors influencing the interaction between the main and side bodies.In order to study the details of the flow field around the trimaran hull and the interference between the main and side bodies,the computational fluid dynamics(CFD)software STAR-CCM+is used to conduct numerical simulation of the trimaran and the main hull at different speeds.The flow field information among the hull and the main and side bodies is extracted,obtaining the wave making and vertical velocities of the cross section and the evolution of the cross section vector streamline at different speeds The differences of flow field between the trimaran and a monohull is studied,and the disturbance of trimaran’s mid hull to the flow field of single main hull is analyzed,obtaining the regularities of wave making of trimaran hull and the change of flow field streamline with speed.This study provides reference for the resistance performance of trimaran and the optimization of overall layout.
