摘　　要：以势流兴波阻力理论中的Rankine源方法为计算基础,利用SHIPFLOW软件模拟了某大型集装箱船的周围流场,考虑流体粘性及自由表面影响,预报了集装箱船的船模阻力。选择三种船体网格(FM,MM,CM)进行船体表面网格划分,采用势流理论与粘流理论的分区分步计算方式(ZONAL法),将数值计算的船舶总阻力值与船模试验值进行对比。计算结果表明网格划分形式MM的计算结果最为准确,同时也验证了SHIPFLOW软件求解技术的可靠性并提高了计算效率。最后选择MM网格划分形式,基于改造母型船法,对原球艏形式进行了改型,计算结果表明:改型球艏船型较原始船型具有更好的阻力性能,达到了船型优化的目的。Based on Rankine source theory for potential flow, the software SHIPFLOW is used to simulate the flow field around a large container ship, while resistance of the ship model is predicted, with free surfaces and fluid viscosity taken into account. Three sets of hull grids (FM, MM, and CM) are adopted, and the ZONAL approach is applied to combine the calculation of potential flow with that of viscous flow. A comparison between numerical calculation and model test in resistance is carried out, and it is shown that the calculation results with MM meshing are more accurate. Reliability of solution techniques by software SHIPFLOW is verified, and calculation efficiency can be improved. For the purpose of hull form optimization, resistance of a new ship with modified bulbous bow shape is forecasted, and better resistance performance is achieved.
