Simulation of Flow past a Cylinder for various Reynold's Number in SolidWorks

TAKEN INPUTS:

Diameter = 0.04 m
Length = 0.1 m
Density of Air = 1.225 kg/m3
Dynamic Viscosity = 18.6e-6 Pa.sec at 20 Degree Celsius
Reynold No. = 20, 40, 100

We know that, Reynold No. = (Density x Velocity x Diameter)/Dynamic Viscosity

By applying above inputs in the Formula, we obtained:

Velocity for (Re = 20)  is  0.007592 m/sec
Velocity for (Re = 40)  is  0.015184 m/sec
Velocity for (Re = 100) is  0.037959 m/sec

Since, Flow through Time = Length/Velocity

Flow through Time for (Re = 20)  is  13.172 sec
Flow through Time for (Re = 40)  is  06.586 sec
Flow through Time for (Re = 100) is  02.634 sec

And, Simulation Time = 2 x Flow through Time

Simulation Time for (Re = 20)  is approx  27 sec
Simulation Time for (Re = 40)  is approx  14 sec
Simulation Time for (Re = 100) is approx  06 sec
