纵倾节能是一种高效易行的船舶节能手段，针对纵倾节能应用，采用基于RANS求解的数值模拟方法，对不同缩尺比与纵倾角度工况下的双尾鳍内河船型绕流场进行了数值模拟。本文分析纵倾角度对阻力及其成分的影响规律；分析阻力随纵倾角度变化规律的原因并对纵倾节能相关的尺度效应进行探讨。结果表明，双尾鳍船舶以设计航速航行时，纵倾角度为首倾1.5°左右时阻力最小，且纵倾节能存在明显的尺度效应。
Trim energy saving is an efficient and accessible means of saving energy in ships ,for the application of trim energy saving, this paper is based on the numerical simulation method of RANS solution to simulate the flow field of twin skeg inland ships under different scale and trim angle conditions. The paper has discussed the influence of the trim angle on the resistance and its components; analyzed the reasons for the variation of the resistance with the trim angle and discussed the scale effect related to the trim energy saving. The results show that for the twin skeg ship discussed in this paper, when sailing at the design speed, the resistance is the lowest when the trim angle is about 1.5°, and there is an obvious scale effect for the ship's trim energy saving.
