Damping force exerted by a viscous medium upon an oscillating cylinder
Abstract
The damping force which an unlimited, homogenous, incompressible, and viscous medium of certain density and kinematic viscosity exerts on an oscillating, infinitely long, stiff, circular cylinder was determined for offshore purposes. The oscillation amplitude is supposed much smaller than the cylinder radius. Three fields, characterized by order magnitudes of the so-called flow Reynolds number Rs, were distinguished: Rs much less than 1, Rs = 0(1), and Rs much greater than 1. Solutions for the related flow functions and corresponding expressions for the damping force are discussed.
