Online calculator for the heat transfer coefficient
in the slot between parallel isothermal plates.
The results in the
intermediate region between laminar and turbulent flow,
(Re=2000 - 2500), are somewhat jumpy but this is a
reflection of the natural uncertainty in that region.

General
Flow between parallel plates may seem to be a simple heat
transfer case. There are nevertheless many flow types
to consider. Laminar or turbulent flow is one example but the
difference between the fully and the developing flow regions
is also important. The correlations used must
in addition converge towards the single plate case when the air
gap is large.
Given this complexity it is virtually impossible to present
a set of equations that link all cases smoothly. This matter is
dealt with in chapter 6 of the
theory document.
