摘　　要：以通用流体软件STAR-CCM+为平台,以瓯江下游的浅吃水肥大船为对象,进行了考虑自由面的船舶阻力性能分析,计算结果与深水试验结果能够吻合良好。考虑实际航道水深较浅,比较了深水状态和浅水状态下阻力的差异,分析了浅水中船舶阻力和各阻力分量的变化以及浅水对兴波的影响,为新船型设计和主机选型提供参考依据。Taking a shallow-draft ship as the subject, the ship resistance performance with the free surface is analyzed based on the STAR-CCM＋ platform. The calculating results agree well with the conclusions drawn from the deep-water experimental data. Considering the shallow water of the real course, the paper compares the difference of the resistance in the deep water and the shallow water. It analyzes the change of the total resistance and the relative component resistance in the shallow water, as well as the impact of the shallow water on the wave-making, lt provides reference for the design of new ship type and the selection of main engine.
