| 摘 要： | 设计并制作了超级导流管试验模型,进行了船舶光体阻力和自航试验以及加装超级导流管的船模自航试验。在不同航速时,研究了超级导流管几何形状和纵向安装位置对其节能效果的影响。试验结果表明:在船尾加装超级导流管可以起到节能的效果,并且以12o开角的超级导流管处于中间位置(位于螺旋桨盘面前,与螺旋桨直径的比值分别为0.2232)时节能效果最佳。

| Abstract: | Super Stream Duct(SSD) was a new-type hydrodynamic energy-saving device. This paper designed the test model of Super Stream Duct. The resistance trial and the self-navigation trial of the model ship with the super stream duct equipped were proceeded. The influences of geometry shape and the installation position of SSD on the energy-saving effect was analyzed at different flow speeds. The experimental results have shown that the Super Stream Duct can save energy when the ship installed the SSD. When the open angle of profile was 12°, the distance between the SSD and propeller disc was 40mm(l/D=0.2232), the effect of saving energy was the best. |
