Flow Induced Vibration Characteristics of a Cylinder in Cross Flow at Low-reynolds Numbers

چکیده
In this paper we present numerical results of the dynamic response to fluid forcing on an elastically mounted rigid cylinder in low-Reynolds flow, allowed to oscillate transverse to a free stream. A vortex method is implemented to solve the two-dimensional Navier-Stokes equation in terms of vorticity. The Reynolds numbers ranges from 90 to 170, a regime that is fully laminar. The vortex pattern for different Reynolds number (Re) is also investigated. We found that in synchronous regime in this range of Re unlike turbulent regime where vortex shedding mode is of 2P and S+P type, vortex shedding mode is of 2S and C(2S) type. The numerical results exhibit acceptable agreement with available experimental data.

An adaptive fuzzy sliding mode controller (AFSMC) is adopted to reduce the 2D flow-induced vibration of an elastically supported square-section cylinder, free to oscillate in stream-wise andtransverse directions in both lock-in and galloping regions. The AFSMC strategy consists of a fuzzy logic inference system intended to follow a sliding-mode controller (SMC), and a robust control syste...
