摘要 采用基于Menterk-ωSST两方程湍流模型的DES方法对粘性不可压缩流体的圆柱绕流问题进行数值模拟,通过对所得的速度场、压力场、阻力系数、升力系数、斯特罗哈数St等结果的分析及与文献上的实验和计算数据的比较,说明DES方法对于低雷诺数及高亚临界雷诺数的圆柱湍流流动是合理的。 In this paper, DES method based on Menter's k-ω SST two-equation turbulence model is used to simulate the incompressible viscous flow around circular cylinder. With the comparison between the experimental data and other numerical data, the analysis results show that DES method is acceptable for turbulent flow with low or higher sub-critical Reynolds number.
