摘　　要：基于CFD数值模拟,从阻力、自航等方面对一艘10000吨级客滚船进行了附体水动力性能优化,并和模型试验进行了比较。首先采用自航数值模拟,优化客滚船的舵以及轴支架的攻角,获得了最佳的附体布置方案。然后采用CFD模拟获得该船带或不带附体时的阻力、螺旋桨敞水特性以及不同螺旋桨旋向时的收到功率。CFD模拟与模型试验比对分析表明,论文提供的方法能可靠地预报不同方案中的阻力、自航等变化趋势,为客滚船附体水动力性能优化提供了新思路。In this paper, hydrodynamic optimization of appendages on a ROPAX was carried by using CFD and model test. Appendages were composite of rudders and V-strut with two brackets. Commercial software SHIPFLOW was adopted for predicting resistance, flow fields, and delivered power. Influence of attack angles of the rudder and the bracket was investigated to obtain an optimal arrangement for rudders and brackets. A comparison between CFD and model tests in total resistance, flow fields, open water performance and delivered power of the propeller was carried out. Well prediction of variants and changing tendency is shown by using the provided CFD method.
