On the maximum amplitude for a freely vibrating cylinder in cross-flow
چکیده انگلیسی
The response of a freely oscillating circular cylinder (“free vibration”) in cross-flow has been studied experimentally using controlled magnetic eddy current to provide variable damping. In general, the nondimensional response amplitude, A*, and dominant frequency, ω*, depend on the Reynolds number, Re, and the nondimensional mass, m*, damping, b*, and elasticity, k*, of the system. The main objective of this study is to characterize the maximum amplitude that is achieved for a given system as cross-flow velocity is varied. We find that this maximum amplitude, Amax*, occurs within a small range of values of keff*=-ω*2m*+k*. For values of Reynolds number in the range 525
