采用缠绕的方式进行螺旋桨的三维建模,相比较传统的坐标转换方式,其符合螺旋桨叶面成型的原理,建模精度较高。利用FINE/Turbo软件对螺旋桨的三维模型构建全六面体多块结构化网格,采用多重网格数值计算方法,显著提高了计算收敛速度。计算获取了螺旋桨的敞水性征曲线,并与实验值进行对比,其结果表明,基于FINE/Turbo软件的螺旋桨数值计算方法预报值和实验数据吻合良好,具有工程实用价值。分析螺旋桨桨叶的静压分布和流场信息,为后续相关研究提供理论指导和技术支持。

Three dimensional modeling of propeller using winding mannercompared with the traditional way of coordinate conversion,the winding method meets the principle of propeller molding and has higher precision. Creating all hexahedral multiblock structured grids of three dimensional model of propeller based on FINE / Turbo software and using the multigrid numerical calculation method,significantly improve the convergence speed. Compared with the experimental values,the calculation results show that the numerical calculation method of propeller based on FINE / Turbo software prediction values are in good agreement with the experimental data,which has practical value in engineering. Finally the article analyses the staic pressure distribution of propeller blades and the flow field information to provide theoretical guidance and technical support for the follow-up study.
