为研究在不同漂角条件下纵倾状态对集装箱船阻力的影响，以KCS集装箱船舶为例，利用RANS数值方法对KCS船模在不同漂角条件下纵倾对船舶阻力的影响进行数值研究。计算船舶初始平吃水时船舶阻力，将所得数值试验结果与已有数据对比，验证数值方法的有效性。基于此方法计算不同漂角条件下船舶在不同纵倾角状态下的船舶阻力值，结果表明，在不同漂角下纵倾角度变化使得船首两侧的受力不等导致压阻力变化显著，并且船舶最小阻力的最佳纵倾角随漂角度而变化。
In order to study the influence of trimming state on the resistance of container ships under different drift angles, taking KCS container ships as an example, the RANS numerical method is used to study the influence of trim on the resistance of KCS ship models under different drift angles and calculate the ship resistance at the initial even keel. The numerical test results are compared with the existing data to verify the effectiveness of the numerical method. Based on this method, the ship resistance under different trimming angles at different drift angles is calculated. The results show that the pressure resistance changes significantly due to the unequal forces on both sides of the bow when the trimming angle changes at different drift angles and the optimal trimming angle of the minimum resistance of the ship changes with the drift angle.
