Simulation of transverse self-oscillations for a free circular cylinder mounted with a narrow gap in a plane channel

Abstract: The experimentally observed self-oscillations of a cylinder mounted with a narrow gap in a plane channel are simulated. The added masses of the cylinder are calculated in the framework of ideal fluid theory by a generalized image method. In order to describe the self-oscillations in a real fluid, some dissipative factors and an impulsive impact force exerted on the cylinder are introduced.

Key words: cylinder, channel, added mass, flow, self-oscillations.
