主　　题：Aerodynamics CFD Shock-buffet 

摘      要：The unsteady transonic aerodynamics of a wing-body configuration is investigated by solving the Unsteady Reynolds-averaged Navier-Stokes equations closed with the full Reynolds Stress *** work presents the prediction of flow field characteristics during deep shock-buffet penetration of a transport aircraftrepresentative *** number of 0.85,and Reynolds number of 5 million based on the mean chord,are selected to reproduce experimental test conditions that serve as validating *** results obtained give information about both surface and flow field shock-buffet *** unsteady shock front is observed on the suction side of the wing which gives birth to the so-called buffet *** field characteristics are dominated by the presence of lambda-shaped shocks and fully separated boundary layer over a significant part of the wing.
