Simulation of Transverse Self-Oscillations for a Free Circular Cylinder Mounted with a Narrow Gap in a Plane Channel / Kharlamov A.A. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2010. № 3. P. 60-63 [Moscow Univ. Mech. Bulletin. Vol. 65, No 3, 2010. P. 67-69]. 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.
