Forced Convective Heat Transfer Characteristics of Water Through a Minichannel at Higher Reynolds Number.
TL;DR: In this article, the authors measured the pressure drop and convective heat transfer coefficient of water flowing through a uniformly heated circular minichannel in the turbulent flow regime, and the experimental results show that the data for water friction factor show a good agreement with analytical predictions from the Darcy's equation for single-phase flow I.
