Navier–Stokes based computer simulations are conducted to determine the aerodynamic
flow field response that is observed for a NACA0012 airfoil that undergoes prescribed
harmonic oscillation in transonic buffeting flows, and also in pre-buffet flow conditions.
Shock buffet is the term for the self-sustained shock oscillations that are observed for certain
combinations of Mach number and steady mean flow angle of attack even in the absence of
structural motion. The shock buffet frequencies are typically on the order of the elastic …
