| description | The present paper is Part 2 of a two parts paper on flow around vibratingwind turbine airfoils. The first part of the paper dealt with a forced oscillatingairfoil. Part 2 focuses on free vibrating airfoils. The flow induced vibrationson two airfoils used for wind turbine blades are investigated by applying afluid structure interaction approach. A commercial Computational FluidDynamics (CFD) code is coupled to a computational structural programthat solves the dynamic equations of the airfoil oscillations. The fluidgoverning equations are described in the Arbitrary Lagrangian Euleriancoordinates and solved with a moving mesh. A straightforward meshingtechnique is implemented in a subroutine called by the CFD code at eachtime step for updating the grid. The method is applied to a free pitchoscillating airfoil and to combined pitch and vertical oscillations known asthe flutter instability. |
