| 摘 要： | 为快速、简便、低成本地获取螺旋桨多种工况下推力系数和转矩系数,根据螺旋桨基本参数,推导并建立空间三维螺旋桨型值点数学模型,并采用Matlab语言进行编程,将计算得到的型值点导入前处理软件,建立光滑的三维螺旋桨模型.以某型AU桨为研究对象,运用计算流体动力学(CFD)方法对其在黏性流场中的正车前进、正车后退、倒车前进及倒车后退4种工况的敞水性能进行数值模拟,给出不同进速系数时的推力系数、转矩系数、桨叶表面压力分布.结果表明,绝大部分计算值与试验值吻合良好,可满足工程应用的要求.

| Abstract: | To obtain the thrust and torque coefficients of open water propeller with a fast,simple and low cost way under multi-working conditions,a mathematical model of three dimensional coordinates points was established and programmed by using Matlab based on the basic parameters of propeller.A smooth propeller model was made by importing the points into front end software.Taking an AU model for example,numerical simulations of propeller in viscous flows were carried out by using computational fluid dynamics(CFD) ... |
