Abstract :
[en] A solver has been developed within the OpenFoam framework to compute large amplitude
motion of two-dimensional rigid configurations. The results obtained with this code
were successfully validated on rigid airfoils at static and dynamic conditions, as well as
correlated with experimental data and numerical solutions from similar unsteady solvers.
The results demonstrated that while current computational methods are able to predict the
self-sustained oscillations characterizing a pitch-dominated stall flutter, including energy
transfer, improvements are needed. The influence of grid, temporal integration, turbulence
modeling, and flow equations is examined for the stall flutter starting solution of dynamic
stall.
