Abstract
The problem regarding the numerical simulation of a circular profile motion in a liquid flow has been studied. To calculate the flow and the aerodynamic loads acting on the profile, the vortex element method is used. The phenomenon of wind resonance has been examined. The investigation has revealed the range of self-frequencies of the circular profile fixed elastically, under which the periodical aerodynamic forces caused by Karman vortexes descend and initiate the resonance aeroelastic oscillations of the profile.
