摘要

This article constructs detached eddy simulation (DES) and delayed detached eddy simulation (DDES) method based on one-equation turbulence model, which uses turbulence model to describe the small-scale movement near the wall. In the separated flow region, the method uses Smagorinsky large eddy simulation with sub-grid scale stress model function, simulating the characteristics of subsonic eddy flow at large angle of attack. The simulation capability of Computational Fluid Dynamics (CFD) on the development, breakdown of eddy and the development and evolution of complex eddy is validated using the blunt edge of the 65° delta wing at high angle of attack. The numerical simulation results indicate that the blunt edge of the 65° delta wing at high angle of attack. The numerical simulation results indicate that the method used in separated flow simulation is reliable.
