使用Fluent软件的螺旋桨敞水性能计算分析

Calculation and analysis of the open water performance of propeller by CFD software Fluent

船舶性能CFD计算领域有必要尽快形成螺旋桨敞水性能CFD计算的快速预报能力,以快速响应用户的需求,使CFD成为螺旋桨设计的手段之一,并利用这一手段,发挥CFD计算结果信息量大的特点,对螺旋桨进行相关的性能考察计算。文章介绍了中国船舶及海洋工程设计研究院利用Fluent软件在螺旋桨敞水性能计算中的计算流程,以某船所使用的侧斜反弯扭桨作为研究对象,给出了敞水性能曲线的计算结果,并与试验测量值作了比较,文中还介绍了对此桨的性能情况所进行的一些数值计算考察。

It is important in the research of propeller to predict numerically the open water performance, In order to respond quickly to the query service for the customers,and also make CFD one of the means of the propeller design,it is necessary to bring CFD fast prediction ability of the open water performance of propeller into the design process of propeller.By employing CFD software of Fluent,the calculation process of the open water performance of propeller is dew;loped in MARIC （The Marine Design ＆ Research Institute of China）,whieh is introduced in this paper.A propeller with high skew and rake tip is typically studied. Comparison of the open water performance curve of the propeller is made between calculated results and measured value.The related investigation to the open water behaviors of the propeller is also reported.
