基于拼接网格的孤立螺旋桨特性研究
|
摘要
以某型螺旋桨为研究对象,采用CFD方法对螺旋桨滑流进行数值计算。利用分区拼接网格技术对螺旋桨旋转区域和外流场域进行网格划分及拼接;在此基础上采用雷诺平均N-S方程,雷诺应力项采用RNG k-ε湍流模型,基于滑移网格方法开展了针对不同高度、不同来流速度及桨叶角的仿真计算。仿真结果表明,数值计算的螺旋桨特性数据与风洞实验数据整体趋势吻合度好,满足工程应用要求,可为后续安装条件下螺旋桨的拉力研究提供参考依据。
This paper used a propeller as the research object and the numerical calculation of propeller slipstream was carried out by using CFD. The splicing grid technology was used to splice the rotating area and static area of the propeller. Based on this, the Reynolds average N-S equation is used, Reynolds stress turbulence model was adopted, and the sliding grid method was applied to the simulation calculation of different heights, speed and propeller angle. The study shows that characteristic data of the propeller obtained by numerical simulation matches well with the overall trend of the wind tunnel experimental data, meets the requirements for engineering application, and could provide reference for the research of the propeller thrust under the installation condition.
