摘要
以KCS船型为研究对象,基于STAR-CCM+软件进行数值模拟计算,运用控制变量法对船舶在开放自由度条件下分别进行了平浮状态以及变纵倾状态的阻力预报。通过对相同航速、不同纵倾所对应的船舶阻力进行预报,绘制出纵倾-阻力曲线,得出在开放自由度条件下船舶以设计航速运行时,艉倾0.1°为最佳纵倾,节能效果达到0.34%。
Taking KCS model as research object to carry out numerical simulation based on STAR-CCM+.Using the control variant method,the resistance of the vessel under the keel and trim conditions were forecasted respectively in the condition of open freedom.Through prediction resistance in different trim angles with the same speed,the trim-resistance curves were obtained.It was shown that,in open freedom conditions,when the vessel is running at the design speed,0.12 degree is the best trim;the energy saving effect can reach to 0.34%.
