Hi guys,
I would appreciate much if you can explain me why fluent has calculated me flow of air and indicate under pressure on the bent cross cuts of the pipe (as on the pics)?
What is the "proffesional" explanation for this?

Basic information about the flow:
fluid - air (150C)
velocity inlet - 35m/s
inner dia of pipe -25mm

I would be after I have done the report my computer died.

What is the explanation for this? I mean if we assume calculation is right how to explain this?

Is this regarding centrifugal force and air having a mass?
