CHN-T1 标模的数值计算及气动特性研究
Numerical simulation and aerodynamic performance analysis of the standard model CHN-T1
摘要
Abstract
Based on the computational tasks of the "1 st Aeronautics CFD Credibility Workshop (AeCW-1)",the aerodynamic performance analysis of the standard model CHN-T1 is evaluated using the provided structured grid and CFL3D flow solver.The grid convergence results show that the SST turbulence model has better performance than the SA model.The buffet study shows that the interference of shock wave/boundary layer appears from the middle of the wing span,and the shock wave continues to increase its strength with increasing angle of attack.The aft loading decreases rapidly in buffet state, which causes the deterioration of control performance.The elastic deformation mainly effects the strength of shock wave and lift distribution in span direction.Under the condition of large Reynolds number,the aft loading area of the pressure coefficient increases,and the suction platform of pressure coefficient decreases, leading to a low drag coefficient.关键词
