Pipe Flow in Solidworks

In the given problem, pipe of outer diameter 100 mm and thickness 5 mm was considered. Simulation is carried out for flow of air through the pipe.

3 cases were analysed where Reynold's number has been varied in each case.

1) Re=100, Velocity=0.0164 m/s

Velocity profile

Velocity at 85%, 90% and 95% of length

As seen from the images above, the velocity at these sections is more or less same. This is because fluid flow is fully developed at early stage and hence velocity will not change much at these locations.

This can be clearly seen in comparision graph below:

2) Re=1000, Velocity=0.164 m/s

3) Re=10000, Velocity=1.64 m/s
