摘　　要：为了能从根本上解决压载水带来的问题,研究人员提出了无压载水船的设计方案。采用STAR-CCM+数值模拟法,研究V型无压载水船的阻力性能。通过STAR-CCM+计算26 000 DWT常规油船的阻力,验证STAR-CCM+软件计算阻力的可行性和可靠性;计算系列V型无压载水船的阻力,并研究其随底倾角的变化规律;最后,以球鼻艏的长度和最大宽度为自变量变换球鼻艏,研究球鼻艏的长度和最大宽度对V型无压载水船阻力的影响。结果表明,设计的V型无压载水船总阻力比母型船有所增加,总阻力随底倾角的增加而增加,可通过优化球鼻艏改善V型无压载水船的阻力。研究结果为V型无压载水船的设计提供了一定的参考。In order to fundamentally solve the problems caused by ballast water, ship researchers propose a design plan for a non-ballast water ship. The resistance performance of the V-shape non-ballast water ship is studied by STAR-CCM+ numerical simulation. The resistance of the 26 000 DWT conventional oil tanker is calculated by STAR-CCM+, and the feasibility and reliability of the STAR-CCM+ software to calculate the resistance are verified. The resistance of the series V-shape non-ballast water ship is calculated, and the law of the variation for the resistance with the bottom inclination angle are obtained. Finally, the bullous bow is changed with the length and maximum width of the bullous bow as the independent variable, and the influence of the length and the maximum width of the bullous bow on the resistance of the V-shape non-ballast water ship is studied. The results show that the total resistance of the designed V-shape non-ballast water ship is higher than that of the mother ship, and the total resistance increases with the increase of the bottom inclination angle. The resistance of the V-shape non-ballast water ship can be improved by optimizing the bullous bow. It provides some reference for the design of V-shape non-ballast water ship.
