摘　　要：以布缆船作为研究对象,使用CFD软件FineMarine计算布缆船在静水中不同航速时的阻力。选取DTMB5415模型进行数值仿真计算,运用二因次法进行换算并与实验值进行对比,证明该方法可以有效预估船舶的阻力。将该数值方法运用于布缆船模型,计算出不同航速下的阻力并分析。结果表明,使用Fine Marine软件对布缆船进行阻力性能预报,具有计算速度快、精度高的优点。计算方法对于船舶的阻力性能研究以及布缆船船型设计和优化有参考意义。Taking the cable distributing ship as the research object,Fine Marine,a CFD software,is used to calculate the resistance of the cable distributing ship at different speed in still water.In the calculation process,the DTMB 5415 mod-el is firstly selected for numerical simulation and compared with the experimental value,which proves that the method can effectively predict the ship resistance.Then the numerical method is applied to the model of cable distribution ship to calcu-late and analyze its resistance at different speeds.The calculation results show that Fine Marine software has the advantages of high calculation speed and high precision in the prediction of the resistance performance of the mooring ship,which can be popularized and applied in the resistance estimation of the mooring ship.The calculation method and results have import-ant reference and guiding significance for the research of ship resistance performance and for the design and optimization of cable distribution ship.
