| 摘 要： | 尾板是加装在高速排水型船尾封板端板处沿船体向后延伸的一块短板,是一种方便和简单的节能措施,本文主要研究其节能的原因.通过大量的模型试验结果分析和对某舰有无尾板的CFD理论计算,并与高速水面快艇加装尾板减阻机理的比较发现:排水型船的节能机理有所不同,尾部压力分布的变化是高速排水型船加装尾板节能的主要原因.

| Abstract: | A convenient and simple energy saving method on high speed displacement ship is to install stern flap which is a shot board fixed backwared on the ship stern slong the hull. The main subject of this paper is to study the mechanism of energy saving by installing stern flap. Through the analysis of large numbers of model test results and the computation of a ship with or without stern flap,it is found that the installation of stern flap changes the pressure distribution of the afterbody of the ship hull,this is the main mechanism of energy saving by installing stern flap on high speed displacement ship,which is different as compared with the fast craft. |
