本文基于CFD技术对3D粘性数值波浪池及位移高速船增阻进行了研究。采用数值造波方法模拟波浪池入口处的波速，在波浪池后部采用人工阻尼区结合解析网格进行消波，采用VOF(Volume of Fluid)方法处理自由液面，利用动态网格技术和运动控制程序对垂荡和纵摇运动进行模拟。对wigleyIII和model5b船模在规则航向波中进行了计算，并将计算结果与试验值进行了对比分析，为排水型高速船在规则波中附加阻力的计算提供了参考。
This paper works on 3D viscous numerical wave tank and added resistance of displacement high-speed craft based on the CFD technology。A numerical wave-generating method is used to simulate wave velocity in the tank entrance,an artificial damping zone is utilized in wave tank rear combined with parse grid to dissipate waves;VOF(Volume of fluid) method is adopted to deal with the free surface.The heave and pitch motion are simulated with dynamic mesh technology and motion control program.Finally the heave and pitch motion and added resistance of the wigleyIII and model5b ship models in regular heading waves is calculated,and the result are compared and analysised with the experiment value.This paper provides reference for the computation of added resistance in regular waves of displacement high-speed craft.
