Thanks Glen for replying.

Yes, you had already pointed out that using turbulence models in low flow Re is not a good idea.

So I am
a) using laminar flow model for the lowest inlet Re of 600...

@Graham81
The optimized design will of course be the one with minimal pressure drop and maximum heat transfer from solid to fluid.
However, which one of these is given more importance will depend...

Well, the conditions upstream of the inlet are not known as yet.
But it will definitely not be fully developed flow.
At present I am using uniform velocity inlet.
While simulating for conditions 2...

Just for clarification:

The first figure above is the variation of Re at inlet and the second figure is the variation of Re at slot nozzle

Optimize for laminar flow, assume it valid for turbulent flow?

Hi,

I want to optimize a design for convective heat transfer and pressure drop.
I have four designs..design 1 ,2,3 and 4.
I want to judge how these designs compare at different inlet Re numbers....
