| 摘 要： | 计算网格和湍流模型是影响CFD结果不确定的重要因素。基于NHLP-2D高升力翼型开展了数值试验对比研究,采用多块分区方法研究了适用于二维复杂构型的网格拓扑结构和网格分布方法,并在尽量排除网格影响因素的情况下,采用均匀设计方法初步分析了SST模型参数在低速多段翼型绕流流场中的影响大小。研究成果在工程应用中具有一定的参考价值。

| Abstract: | Grid and turbulence model are the important influence diathesis of CFD result uncertainty.This paper has developed contrast study of numerical experimentation on basis of NHLP-2D high-lift airfoil.The grid topology and gird distribution rule are studied by Multi-block partition method for 2D complex configure.And,to the best of getting rid of grid effect,the Influence of parameters in SST turbulence model are analyzed by Uniform design method for low speed multi-element airfoil.The conclusion of the study in engineering application,which has a certain reference value. |
