Numerical simulations for the flows of typical transport configurations are performed by solving Navier-Stokes equation using TRIsonic Platform (TRIP). The purpose is to validate TRIP3.0 for the simulation of transport configurations. The configurations contain DLR-F6 and trapezoidal high lift configurations. For DLR-F6, the structured mesh and test data are obtained from DPW-III. The reference numerical results are obtained by CFL3D. For the high lift configurations, the structured mesh are generated with ICEM, and test data are obtained from HiLiftPW-1. For these configurations, the effects of grid density to aerodynamic characteristics are systematically studied. The numerical results are verified by comparison with experimental data and numerical results of CFL3D. Grid refinement leads to converged numerical results. It is demonstrated that grid density has little influence on friction drag, whereas significant influence on pressure drag for the DLR-F6 configurations. It has little influence on lift and momentum for the trapezoidal high lift configurations before stall, but has obvious influence near stall. |
