In a wavy surface structure, the wavelength and amplitude measures have a direct effective factor on the heat transfer rate. Air flows through a corrugated duct in a wavy shape from the top and bottom sides of the tunnel. The question is: what is the optimum expected ratio for these two factors to reveal the best thermal performance in the high Reynolds number zone?
Thanks for your contribution
hi Ali,
I have read related work from C. C. Wang, please check out his work. It might be useful for you.
I have some links of the same, there much more available online.
Regards,
Rajesh.

You can also find good information in the book by William Kays and A.L.London, Stanford University. Title: COMPACT HEAT EXCHANGERS.
May I add that what I mean with corrugated profil is a corrugated crossed (so called C-C-profile). That is extremely overkilled. A optimized profile is the FNC-profile. But even the DU-profile can be as good as the FNC by having the right data. I think the ARVOS group in Germany knows a lot of that.
