| 摘 要： | 本文提出具有壁面切向喷流的船用舵水动力学计算的一种方法,其中用Theodorsen方法求解钝尾有分离的势流问题。用Spalding统一边界层理论作粘性计算,以及用Lighthill的当量源方法考虑粘性/势流的耦合效应。通过对一个特定舵的计算,发现壁面喷流对提高舵效有较大潜力,预测了壁面喷流舵在船舶应用上有其研制开发的前景。

| Abstract: | This paper presents a hydrodynamic calculational method of ship rudder with tangential wall-jet. Theodorson's method is used to solve potential pressure distribution of separation flow around the blunt tailed rudder. The viscous flow problem is calculated by modified Spalding's unified boundary layer theory. The viscous/inviscid interaction is considered by using Lighthill's equivalent source method. A special rudder is calculated. It is found out that wall-jet has potentiality to improve rudder efficiency and the future of developing the wall-jet rudder in ships is predicted. |
