【摘要】：主要开发了SST-DES和SST-DDES两种分离涡方法,并集成到基于开源代码平台Open-FOAM开发的CFD求解器naoe-FOAM-SJTU中.选用高Reynolds(雷诺)数下串列双圆柱绕流问题作为标准算例来验证所开发的分离涡方法.该标准算例此前在美国国家航空航天局兰利研究中心的两个不同风洞做过物理试验.该研究将数值模拟得到的时均流场信息和一些其他物理量同物理试验结果比较,同时讨论分析了三维瞬态流场结构.结果表明该文开发的SST-DES和SST-DDES分离涡方法能够解决高Reynolds数下有大量流动分离的复杂流动问题.
[Abstract]:Two vortex separation methods, SST-DES and SST-DDES, are developed. And integrated into the CFD solver naoe-FOAM-SJTU based on the open source code platform Open-FOAM. The developed separation vortex method is verified by a numerical example of the cascade double cylinder flow problem. The standard example was previously tested in two different wind tunnels at the Langley Research Center of NASA. The information of time-averaged flow field and some other physical quantities obtained by numerical simulation are compared with the results of physical experiments. At the same time, the three-dimensional transient flow field structure is discussed and analyzed. The results show that the SST-DES and SST-DDES vortex separation method developed in this paper can solve the complex flow separation with a large number of high Reynolds numbers.
