摘要
Abstract
The aerodynamics simulation of an aircraft was performed in a given attack angle and Mach number by means of the single-equation (Spalart-Allmaras) model in turbulence model and CFD software Fluent. First,Spalart-Allmaras model is used to achieve the mathematical modeling for the flow field of the aircraft,the Fluent software package,Gambit is adopted to conduct the geometric modeling of the aircraft’s outline,and then meshes are generated and the boundary conditions are set. Fi-nally,the relevant parameters are set in Fluent,and lift coefficient,drag coefficient,pitching moment coefficient,and pressure and flow velocity distribution on the aircraft surface are obtained by the aerodynamic numerical calculation and simulation. The simulation results also need to be analyzed. The research result demonstrates the Spalart-Allmaras model can achieve the aerody-namic numerical calculation of the aircraft with wall-surface restriction.关键词
