| 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. |
