Abstract
The phenomenon of low amplitude self-sustained pitch oscillations in the transitional Reynolds number regime is studied numerically through unsteady, two-dimensional aeroelastic simulations. Based on the experimental data, simulations have been limited in the Reynolds number range 5.0×104 ► Aeroelastic LCOs of a NACA0012 at transitional Re are simulated with a URANS FSI code. ► The airfoil oscillates in pitch with small amplitude. ► Laminar boundary layer separation plays a key role in initiating the LCOs. ► Turbulence inhibits the LCOs. ► von Kármán vortex shedding has no impact on the LCOs.
