摘　　要：以某大型散货船为研究对象,通过模型试验和数值模拟对2种模型尺度下由前置定子与舵球推力鳍组成的组合节能装置的节能效果进行尺度效应分析。研究结果表明:大尺度船模节能装置的节能效果更好;通过模型试验与数值计算得到的安装节能装置前后船舶的各推进性能参数的变化趋势基本一致。从工程应用的角度看,在对带有节能装置的船舶进行快速性试验时,建议在条件允许的情况下尽量选择大尺度船模。The scale effect in model tests and numerical simulations of a large bulk carrier with combined energy-saving devices is studied.The energy-saving performance achieved by the devices is tested and calculated in two different model scales respectively.The test data are compared with the calculation results.The comparison shows that the tests with larger model scale is better in predicting performance improvement and the trends of propulsive performance parameter change caused by the energy-saving devices.From the perspective of engineering application,it is recommended that,within the reasonable range of test conditions,large-scale ship models should be used for towing tank tests of ships equipped with energy-saving devices.
