Flow over a cylinder at different Reynolds number points using Transient Simulations

For the baseline simulation i used air as the fluid and an inlet velocity of 1m/s. The size of the computational domain was set to 2m and the Output time was set for 4 seconds.
The desnity of air is 1.225m/s
The viscosity of water 1.813 x 10^-5 kg/m.s
The diameter of the cylinder is 0.2 m
The Reynolds Number of the baseline simulation is 13513.5135

For V= 1.2 m/s
The Re = 16216.2162
Computational Domain size = 5.5 m
Output time = 9.2 s

For V= 1.4 m/s
The Re = 18918.919
Computational Domain size = 5.5 m
Output time = 7.9 s

For V= 2.0 m/s
The Re = 27027.027
Computational Domain size = 5.5 m
Output time = 5.5 s

For V= 2.0 m/s
The Re = 27027.027
Computational Domain size = 5.5 m
Output time = 35.2s
This is the transistion video of the pressure plot and it is similar for the previous cases as well.

The Flow and pressure contours are similar for all, only the size of the wake region, the region at which the velocity drops signifantly due to turbulence, decreses with increase in Reynolds Number.
