In order to use permeable cylinders instead of solid cylinders, the vortex shedding
in the wake region of only permeable cylinder was investigated inclusively.
Simulations are started in a static fluid field, and the cylinder moves according to (17) until periodic vortex shedding
is established (see Figure 4 for an overview of the vortex shedding

control using jets: a computational study with lattice Boltzmann method," in ASME 2016 35th International Conference on Ocean, Offshore and Arctic Engineering, Busan, South Korea, 2016.
Effect of thermal buoyancy on vortex shedding
behind a square cylinder in cross flow at low Reynolds numbers.
whose Strouhal number equals to that of two-dimensional circular cylinder exists in the wake of the mirror.
Resonance may occur if the vortex shedding
frequency coincides with a natural frequency of the part or structure.
In Figure 7(c), a combined resonance occurs owing to both parametric excitation and vortex-shedding excitation, where both excitations satisfy the condition that can excite resonance of a system under only parametric or vortex shedding
excitation, and its motion amplitude is obviously larger and more unstable than those of the other cases in Figures 7(a), 7(b), and 7(c).
For Re = 100 shown in Figure 10(c), the vortex shedding
is observed for all three particles, but the particles are settling together in the channel, which is different in the case of Re = 200.
Vortex-induced vibration is a resonant phenomenon caused by the periodic vortex shedding
from the structures.
The majority is to study the effect of fixed dividers on vortex shedding
. For the elastic-supported cylinder-splitter plate system, Ding et al.
The motion of the fluid at the edge of the square column is very irregular, which will greatly affect the vortex shedding
near the column wall.
THUNDERSNOW closed airports, roads and schools yesterday - and freak "vortex shedding
" gusts of wind wilted lampposts.
