摘　　要：基于CFD技术,使用SST k-ε湍流模型和VOF方法,设计了7种不同艏柱倾斜角度(艏倾角)的船首方案,通过仿真实验对比了不同船首倾角单体船在静水直航中的阻力特性。仿真结果表明,中低速内倾式船首船体总阻力小,中高速外倾式船首船体总阻力小,全航速垂直船首总阻力最大。Seven bow schemes with different angles(stem post inclination)were designed in this paper,based on CFD technology,the SST k-εturbulence model and VOF method.The simulation results show that the total resistance of medium and low speed inverted bow hull is weak,so is the total resistance of medium and high-speed outward hull.The overall resistance at vertical is maximum.
