Abstract EN
A vacillating forces on the body are causes by The vortex shedding vacillate, and generating a cyclic variation in two directions, cross flow(CF), in same direction of flow and in-line(IL) with direction normal to flow.
Determination of the force components, (CF) and (IL) directions is important when doing further Lock-in state.
As a choice an alternative to response models the Computational Fluid Dynamics (CFD) simulations is presented and can be adopted for vortex induced vibration (VIV) analysis to conquer the restrictions of the status approach of practice engineering.
To estimate the lift and drag coefficients the turbulent flow is simulated depending on shear stress transport(SST) of k-ω turbulence model with characteristics which utilized time dependent test (transient) using ANSYS FLUENT 16.1 and examined at various values of Reynolds number (30, 75, 200 and 1000) with uniform velocities of (0.06, 0.15, 0.4 and 2) m/s to overcome laminar, transport and turbulence regimes.
At Re < 40 no lift force component will effect on the cylinder, then it clearly appears in the regime Re greater than 40
