以KCS船型作为研究对象,使用CFD软件Fine‐Marine计算了不同雷诺数下的阻力值,并对船体尾部流场分布进行分析。在满足全相似情况下计算了不同尺度的船舶阻力值,计算得到的各阻力系数相差较小,速度场基本一致,结果表明,基于C FD的方法,通过改变介质的粘性系数使得不同尺度船舶满足全相似是可行的。

Ship resistance is calculated utilizing CFD software Fine‐Marine ,where KCS ship is taken as the research object .After that ,resistance under different Reynolds numbers and the distribution of flow velocity of the stern were analyzed .Under the condition of full similar ,ship resistance at differ‐ent scales are calculated .And it turns out that the resistance coefficients of different scales are of small difference ,distribution of velocity field is basically the same .T he results show that it is feasible to meet the full similarity condition through the CFD‐based approach by changing the fluid viscosity of different ship scales .This study provides a certain reference for ship resistance calculated research .
