摘 要: 对螺旋桨水动力性能的影响因素进行分析,采用计算流体动力学(computational fluid dynamics, CFD)软件对敞水螺旋桨的水动力性能进行数值模拟。编制FORTRAN程序计算螺旋桨型值点,用前处理器ICEM进行建模,并对网格进行局部加密。在此基础上采用数值模拟方法对影响螺旋桨性能的主要几何参数进行变尺度研究,分析盘面比、螺距比和侧斜等各种参数对螺旋桨性能的影响。计算结果表明:盘面比和螺距比对螺旋桨的效率和推力性能有重要影响,而侧斜对螺旋桨的推力性能影响相对较小。
关 键 词: 船舶与海洋工程;螺旋桨;水动力性能;数值模拟;螺距比;侧斜

Abstract: In order to analyze the influence factors on the hydrodynamic performance of the propeller, the numerical simulation of open water propeller was made using computational fluid dynamics (CFD)software. The value of the propeller point was prepared by FORTRAN program, the propeller geometry was modeled by preprocessor ICEM and the local grid was refined. The numerical simulation method was used to take variable scale research on the main geometrical parameters which affected the performance of propeller. The various parameters which include propeller area ratio, pitch ratio and skewed on the performance of the propeller were analysized. The calculation results showed that the area ratio and pitch played an important role in the thrust performance of propeller, while the influence of skewed was relatively smaller.
Key words: ship and ocean engineering; propeller; hydrodynamic performance; numerical simulation; pitch ratio; skew
