| Abstract: |
| The CFD/CSD coupling method and program based on closely coupling are developed. Hybrid grid finite volume method is used to solve unsteady flow fields, and the dual time stepping method based on LU-SGS implicit scheme is used in temporal discretization. 3D wing's aeroelastic phenomenon is simulated by solving Reynolds-averaged Navier-Stokes equations; the flutter boundary is calculated and agrees well with experimental data. The validity and practicality of this method and program are verified. Based on the Delaunay map and spring analogy, hybrid dynamic grid method is deployed to aeroelastic calculation; the effect of turbulence models in aeroelastic simulation is also studied. |
