Heat Pipe is on a distinguished road
HellO All.

I'm simulating Natural Convection Heat Transfer in Horizontal Concentric Annulus between Outer Cylinder and Inner Flat Tube using Nanofluid but faced some problems:

1- Laminar, Turbulent and Steady-Unsteady but incorrect result.

2- Can consider the Nu avg that calculated from Fluent
3- How to be aware with Nu-Ra correlations
