中文摘要:
      为了能从根本上解决压载水带来的问题,船舶研究人员提出了无压载水船的设计方案。目前,无压载水船仍处在研究阶段,还没有实船运营,对无压载水船的型线设计、阻力性能等方面还需进一步研究。采用STAR-CCM+数值模拟的方法,研究V型无压载水船的阻力性能。首先,通过STAR-CCM+计算26000DWT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;其次,计算系列V型无压载水船的阻力,研究V型无压载水船的阻力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,所设计的V型无压载水船的总阻力比母型船有所增加,总阻力随底倾角的增加而增加,可以通过优化球鼻艏改善V型无压载水船的阻力。研究结果能为V型无压载水船的设计提供一定的参考。
英文摘要:
      In order to fundamentally solve the problems caused by ballast water, ship researchers proposed a design plan for a non-ballast water ship. At present, the non-ballast water ship is still in the research stage, and there is no such ship in operation. Further research is needed on the design and resistance performance of the non-ballast water ship. The resistance performance of the V-shape non-ballast water ship was studied by STAR-CCM+ numerical simulation. Firstly, the resistance of the 26000DWT conventional oil tanker is calculated by STAR-CCM+, and the feasibility and reliability of the STAR-CCM+ software to calculate the resistance are verified. Secondly, the resistance of the series V-shape non-ballast water ship is calculated, and the V-shape non-ballast water ship is studied. The law of the variation of the resistance with the bottom inclination angle are obtained; finally, the bullous bow was 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 was 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. The results can provide some reference for the design of V-shape non-ballast water ship.
