Parallel numerical simulation of oscillating airfoil NACA0015 in the channel due to flutter instability
The work is devoted to 3D and 2D parallel numerical computation of pressure and velocity fields around an elastically supported airfoil self-oscillating due to interaction with the airflow. Numerical solution is computed in the OpenFOAM package, an open-source software package based on finite volum...
