| Abstract: | In this paper,chimera grid technique is applied to viscous flowfield of multi-element airfoils based on structured grid and RANS equations.The low speed viscous flowfields of NLR-7301 two-element airfoils and five-element airfoils are taken as typical computational examples.The numerical results are compared with test data of wind tunnel and numerical results based on 1-to-1 grids.It shows that the chimera grid technique used in the paper has enough precision and reliability. |
