Honorable Mention, Postdocs & Grad Students: Maria Aleman, a graduate student in the College of Engineering, for "Transverse Oscillating Cylinder Vortex Shedding
Control of vortex shedding
downstream of circular cylinders has a great importance and several control methods are used to suppress the pattern effect of vortex shedding
Also, high fidelity models take into account Reynolds number effects and lift and drag fluctuations (10% to 20%) caused by vortex shedding
[11, 12] in the case of flow separation around debris.
 reported on the use of the lattice Boltzmann method, in conjunction with large-eddy simulations, to study an interesting phenomenon related to the suppression of vortex shedding
from circular cylinders with high accuracy coupled with computational efficiency.
In the movement of these vehicles, the interaction between the air and the cylinder is extremely complex, which involves the nonlinear process of flow separation, vortex shedding
, lift oscillation, and so on.
 numerically predicted the effect of aiding thermal buoyancy over a square cylinder at low Reynolds number; the governing equations are solved in unsteady state, the range of Reynolds number is chosen between 5 and 40, the reported results presented that fluid flow becomes unstable when thermal buoyancy is increased, at some critical parameter of Richardson number, periodic vortex shedding
Characteristic dimensionless frequencies, approximately 0.2 are captured in the wake which are close to the Strouhal number of the measured vortex shedding
for a two-dimensional cylinder and larger than that for finite length circular cylinder .
where [[theta].sub.w] is the water density, D is the outer diameter of the cable, [[omega].sub.v] is the vortex shedding
frequency, [C.sub.L] is the vortex-induced lift coefficient, and [v.sub.L] is the vortex flow velocity and its typical value is taken as 1.0 m/s.
It is observed that the vortex shedding
takes place for the lateral particles when t/T [greater than or equal to] 20.
Vortex-induced vibration (VIV) is a resonant phenomenon caused by periodic airflow vortex shedding
whose frequencies are close to the natural frequency of the structures .
It is through the automatic technology to disturb the flow filed, which can control the cylinder vortex shedding
and finally achieve the purpose of vibration suppression.
