Many researchers have experimentally and numerically investigated the flow field around an unsteady airfoil, which is a common unsteady flow. In particular, there have been a number of studies on the flow field around a pitching airfoil, a heaving airfoil and a combination airfoil with combined pitching and heaving motions. In recent years, the flow field in the vicinity of moving airfoils capable of flexible elastic deformation has become a focus of attention. Flow in the vicinity of an elastically deforming airfoil may be understood as a fluid-structure interaction (FSI) problem, and the motion and deformation of elastic airfoils, as well as the associated vortex flow phenomena in their vicinity, are complicated. In this study, we investigate the dynamic behavior of vortices on elastic heaving airfoil in a separation region, at 16 degree of attack angle, by fluid structure interaction simulation using ANSYS 16.1/ANSYS CFX 16.1.
