Validation of Axisymmetric and 3D pipe flow results
 

Hello All,

I am solving simple axisymmetric tube flow which is pressure driven with uniform 5; pressure at inlet and zerGradient at outlet.
The domain in axisymmetry is 5m long and 1m high.
I have got max velocity 0.24 which is exactly half of the one which i got solving full 3D and 2D(5m long and 2m high) where with the same boundary and inlet conditions it was 0.46.

I am using IcoFoam and salome for meshing.

I am new user so any help/or comment will really help me.

Thanks in advance
