| 摘 要： | 本文根据有关文献提出的预旋流的概念,给出了包括横向非对称船型及多桨船型在内的多种船型的桨前流动的预旋转速(或称切向伴流相当转速)的精确计算方法,以及船模预旋转速实船预旋转速间的关系和考虑预旋流动的实船预报,文中还讨论了十八届国际水池会议给出的计算双桨船模型桨前流动的预旋转速的近似性,最后以程序计算的形式,把预旋流概念同时引入自航试验分析和实船预报中。

| Abstract: | Based on the prerotation concept expounded in reference (1),thearticle gives an accurate method for the calculation of prerotation inflowspeed of propeller (or called equivalant wake speed) of many ship typesincluding transversely unsymmetric ship type and multi-propellership type.Italso explains the relation between the prerotation inflow ship model andthat of real ship and makes consideration on the prediction of prerotationinflow on board.Furthermore,the article discusses the calculating similarityof the prerotation inflow speed of twin-propeller ship modelput forward onthe 18th ITTC.Finally,prerotation concept is introduced tothe analysis of self-propulsion test and prediction on board in the form of program calculation. |
