Hello all,
I am working on moving pipe-like geometry. As I need a constant velocity at inlet and outlet or constant velocity profile. I needed to use the velocity of the walls the same as an inlet around 45 cm/s. There is heat propagating inside the pipe.
But now, the problem is, I want to study the cooling of the pipe to atmospheric temperature conditions after heating. So I have specified one more cylinder around the geometry with the velocity at the inlet of the air domain as 0.1 cm/s.
After the simulation has run. I can see a backflow in the air domain at the outlet. I do not know, this is because of the velocity difference or what? Could anyone explain me?
Also if there are any geometry errors please let me know.
(I am attaching velocity contour of the symmetry of the geometry)
Thank you
Raj

Thanks for the suggestion Mr. Maged Gumaan Bin-Saad. I think this is not relevant for my question as in my model, the air is flowing along the pipe and there is no gap between the pipe and air domain. Please excuse me if my explanation is bad or if I misunderstood.
