Dear all,

I am sorry to ask silly question. I am trying to simulate convective heat transfer in laminar flow by Using Ansys FLUENT 17.2.
Here is some details

•Plain tube
•Laminar flow (Velocity: 0.01209669 m/s)
•Working fluid: water liquid
•Internal diameter tube=15.88 mm
•Tube length =8.02 m (7.9 m is entrance region and 0.12 m is the test section)
•Inlet Temperature = 27 C
•Wall Temperature = 17 C
•Reference Temperature = Film Temperature = 22 C
•All Properties are calculated at Film Temperature

But the result is not good. The velocity and temperature profile should be parabolic. I attach some of results.

Do you have any suggestion?

Thank you so much
