Numerical Simulations of flow past a cylinder

I am giving the sample geometry. Then meshing needed to be made so that it could dynamically adjust the motion of the cylinder rotationally oscillating about its axis.

Computational domain:

cylinder square side 1m

height of domain 60 m

upstream dimension 20 m

downstream dimension 40 m

You can alter/modify the domain dimension to get particular results.

Then 3D simulations need to be carried out preferably LES at different flow parameters:

Reynolds number 1000

Frequency ratio: 0.8 (ratio of forcing frequency to natural vortex shedding frequency)

Maximum oscillation amplitude 20

To determine:

Strouhal number

Affect on Coefficient of drag

Affect on Coefficient of lift

understanding the velocity contours
