PARALLEL NUMERICAL COMPUTATION OF DISTRIBUTION OF PRESSURE PAST AN OSCILLATING AIRFOIL NACA0015
Řidký V., Šidlof P.
pages 575 - 578, full text

The article is devoted to 2D parallel numerical computation of pressure on the surface of an elastically supported airfoil self-oscillating due to interaction with the airflow. Movement of airfoil is described by translation and rotation, identified from experimental data. A new boundary condition for the 2DOF motion of the airfoil was implemented in OpenFoam, an open-source software package based on finite volume method. The results of numerical simulation (distribution of pressure on the surface of airfoil) are compared with experimental data measured in a wind tunnel, where a physical model of NACA0015 airfoil was mounted and tuned to exhibit the flutter instability. The experimental results were obtained previously in the Institute of Thermomechanics by interferographic measurement in a subsonic wind tunnel.
