Verification & Validation
Verification and validation is a formal process for checking results. Each of these terms has a specific meaning which we won't get into here. We'll act like high-priced consultants and do the bare minimum: we'll refine the mesh and make sure that the results are nearly independent of the mesh.

Comparison with the experimental measurements is another way you'll check the FLUENT results. |
Refine Mesh
Let's repeat the solution on a finer mesh with smaller cells. In workbench, under Forced Convection project, right click on Fluid Flow (FLUENT) and click duplicate. Rename the duplicate project to Forced Convection Refined Mesh. You should have two project cells in workbench.

Refining the mesh doesn't change the wall temperature much but the centerline temperature changes a fair bit. So another level of mesh refinement would be wise.
