| 摘 要： | 本文提出一种新的船模自航模型化方法以“消除”船－桨干扰总理２的惊工影响，首先讨论船－桨组合体绕流（平均流动）应满足的相似准则，其中引进了两个新的准则以联系船 尾流的特征；尾流宽度与速度亏损，讨论了满足这些准则的模拟条件和方法，给出满足相似条件的船模－实船性能关系式，最后讨论了新模拟方法在船旋螺旋桨空的与噪声模型试验中的应用。

| Abstract: | A new modeling for self-propulsion test of ship has been developed to overcome the difficulty of scale effect occurred to interaction between model propeller and hull herein. At first the similitude criteria which should be met in the model test are discussed. Two of them are new criteria to represent the characteristics of wake:width and velocity defect. Then a new simulation method to meet these criteria has been established. The relationship of performance between model and ship,which interactions achiev... |
