【摘要】：该文基于三种不同的CFD方法:多重坐标参考系法(MRF)、任意网格界面元法(AMI)和重叠网格方法(Overset)对某一四叶螺旋桨的敞水性能进行数值模拟和预报,并对螺旋桨周围的流场进行了分析。其中,对于任意网格界面元法(AMI)与多重坐标参考系法(MRF),分别采用开源CFD计算软件Open FOAM所提供的求解器pimple Dy MFoam与MRFSimple Foam进行计算;对于重叠网格方法(Overset),采用基于Open FOAM平台开发的具有重叠网格模块的船舶与海洋工程水动力求解器—naoe-FOAM-SJTU进行求解。通过与试验结果的对比以及方法间的比较,验证了三种方法在螺旋桨敞水性能预报中的可靠性和有效性,并总结了各方法的特征与优劣。同时也对螺旋桨附近的流场特征进行了讨论与分析。
[Abstract]:Based on three different CFD methods: multi-coordinate reference system method (MRF), arbitrary grid interface element method (AMI) and overlapping grid method (Overset), the open water performance of a four-blade propeller is numerically simulated and predicted. The flow field around the propeller is analyzed. For arbitrary grid interface element method (AMI) and multi-coordinate reference system method (MRF), the solver pimple Dy MFoam and MRFSimple Foam provided by the open source CFD software Open FOAM are used to calculate the grid interface element method and the multi-coordinate reference system method respectively. For the overlapping grid method, (Overset), is solved by naoe-FOAM-SJTU, a ship and ocean engineering hydrodynamic solver with overlapping grid module, which is developed on the Open FOAM platform. Through the comparison with the experimental results and the comparison between the methods, the reliability and effectiveness of the three methods in the prediction of propeller open water performance are verified, and the characteristics, advantages and disadvantages of each method are summarized. At the same time, the characteristics of the flow field near the propeller are also discussed and analyzed.
