摘　　要：为了实现节能减排,需要使用各种手段降低船舶阻力和提高螺旋桨推进效率,论文基于一型支线型集装箱船开展快速性模型试验和数值模拟,探讨船体、螺旋桨和舵三者间距变化对推进效率的影响。研究结果表明,减少螺旋桨与舵的间距有利于提高螺旋桨推进效率;整体往后移动螺旋桨和舵也有利于提高螺旋桨推进效率。数值模拟结果与模型试验结果在应用方案的比较上两者具有良好的一致性。因此数值模拟可作为模型试验的补充,有利于捕捉更佳的布置方案。In order to save energy and reduce emissions,various means were used to reduce ship resistance and improve propeller propulsion efficiency.With respect to a container ship,model tests and numerical simulation were carried out to study the influence of spacing between hull,propellers and rudder on the propulsion efficiency.Obtained results indicated that the decrease of spacing between the propeller and the rudder,that is,shifting the propeller downstream,was prominently helpful in increasing propeller efficiency.Moving the propeller and rudder backwards as a whole was extremely useful to improve the propeller propulsion efficiency.The numerical simulation results were in good agreement with the model test.Numerical simulation could be used as a complement to model tests to capture better layout scheme.
