Aerodynamic characteristics simulation of CHN-T1 model with TRIP3.0

Based on the TRIsonic Platform Version 3.0 (TRIP3.0) software, the flow over CHiNa-Transport (CHN-T1) configuration supplied by the committee of 1st Aeronautic CFD Credibility Workshop, is simulated. The grid convergence is studied by the coarse, medium, fine meshes and the extremely fine one with ten billion grid points. The influence of the tail support, static aeroelasticity of the wing and the Reynolds number effect on the aerodynamic characteristics is investigated by suitable grids. Aerodynamic force coefficient, pressure distributions, and flow patterns on the surface are analyzed. The numerical results agree well with the experimental data. Grid refinement leads to convergence numerical results. It is demonstrated that the tail support has dramatic influence on the moment. The static aeroelasticity of the wing has little influence on the aerodynamic characteristics and Reynolds number effect has obvious influence on the aerodynamic force coefficient.
