Large-eddy simulations of the NACA23012 airfoil with laser-scanned ice shapes
In this study, five ice shapes generated at NASA Glenn's Icing Research Tunnel (IRT) are simulated at multiple angles of attack (Broeren et al., J. of Aircraft, 2018).

Transonic buffet and incompressible low-frequency oscillations at high Reynolds numbers
Coherent, self-sustained oscillations of the flow over aircraft wings can lead to unsteady loads that detrimentally affect aircraft safety and stability, thus limiting the flight envelope.
