I have recently found the link below which reports a collection of Nusselt number correlations for several scenarios. Nothing new under the sun, anyway I rate it as useful
Yup… didn’t realize that section (natural convection and horizontal plates) was completely out of service.And yeah, I think all the correlations are from Incropera P. Dewitt.
I agree it is still a good link as it gathers many useful correlations and it is a quick-reference resource. Anyway I had overrated this before your previous post: the incomplete natural convection section is definitely a not trivial miss.
It's possible that the owner is no longer there. His homepage's list of "recent" activities are in the late 90s. I sent an email to the address there, so...
