With the following boundary conditions:

Duct height (H)=20 mm
Rib height (e)=3 mm (square rib)
p/e=13.3
Inlet length=245 mm
Uniform heat at bottom surface=1100 W/m2
(the surface below a rib is considered insulated)
Aspect ratio (AR)=5
Pitch p=40 mm
Length of test section=280 mm
Outlet length=115 mm
Width of duct=100 mm
Reynolds number=8900.

How can I get the following curves in?
