When is it allowed to treat the heat-transfer coefficient α as constant?
TL;DR: In this article, the heat transfer coefficient α may be treated as constant and the criterial moduli for the slug-flow in a finite length flat duct with prescribed heat flux on the boundary are derived and the ranges of their numerical values are determined.
