随着全球能源和环境问题越来越严峻,航运市场低迷和竞争的日益激烈,节能减排已成为航运业的迫切需求。船舶纵倾优化具有成本低、易实现和效果佳等优点,是一种更好的节能减排方法。以KCS集装箱船在设计吃水时平吃水状态为基础,对船舶分别进行不同纵倾状态调节,利用RANS方法和切割体自动划分网格技术,计算船舶在不同首倾和尾倾状态下的阻力数值。结果表明,在不考虑水深影响的情况下,KCS集装箱船在不改变船舶航速、载重量的前提下,可以通过纵倾优化调节减少船舶阻力。
With the global energy and environmental problems becoming more and more serious, the shipping market downturn and increasingly fierce competition, energy conservation and emission reduction has become an urgent need of the shipping industry. With the advantages of low cost, easy realization and good effect, ship trim optimization is a better method of energy saving and emission reduction. Based on the flat draft condition of KCS container ship in design draft, the different trim conditions of the ship are adjusted. The resistance values of the ship under different ship pitch and stern conditions are calculated by using RANS method and automatic meshing technique of trimmed cell mesher. The results show that the resistance of KCS container ship can be reduced by trim optimization regulation without considering the effect of depth.
