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...

Keywords: Flow around a circular cylinder Vortex-induced vibration Flow control Steady suction Mitigation of vortex-induced vibration a b s t r a c t In the present study, a flow control method is employed to mitigate vortex-induced vibration (VIV) of a circular cylinder by using a suction flow method. The VIV of a circular cylinder was first reproduced in a wind tunnel by using a spring–mass s...
متن کاملDrag coefficient and strouhal number analysis of a rectangular probe in a two-phase cross flow
In some case of laboratory and industrial applications, various kind of measurement instruments must be placed in a conduit, in which multiphase fluid flows. Vortex shedding for any immersed body in flow field is created with a frequency, which according to flow conditions such as flow rates, geometry of body, etc. may be constant or variable. Failure may happen, if this frequency is close to o...
متن کاملEffects Of Frequency Variation At Inlet Flow On The Vortex Shedding Frequency Behind A Circular Cylinder
In many applications the flow that past bluff bodies has frequency nature (oscillated) and it is not uniform. This kind of flow has effects on the formation of vortex shedding behind bluff bodies. In this paper the flow around a circular cylinder was numerically simulated. The effects of frequency variation at inlet flow on the vortex shedding frequency were investigated. The transient Two-Dime...
