My Goal is to find that increasing the Air-gap in a Soda can and Varying Reynolds number ( Velocity ) would affect the Temperature Distribution.

The Air-gap/Temp Relation was perfect ( as I increase Air-gap the Temp cools faster).

Now for different cuts ( here I cut it half ), I run two cases:

Walls = symmetry
Rotating Wall 1 = Rotating at omega ( around x-axis)at a Cte Temp of 274.15
Rotating Wall 2 = Translating at V in Z-D at Cte Temp of 274.15 K
And Temp ( initial )=298.15 K
Check Fig.0 For geometry.

1) Re=0
2) Re=5000

And I got the same Temp Distribution.

Based on Energy Equation, ( T is a function of Re and... ) so anyone knows why I have same Temp distribution?

Check Fig.1 for Velocity Contour
And Fig.2 for Temperature Contour at the mid plane.
