Due to the lack of understanding in the literature of channel height effects on forced-convection boiling and critical heat flux (CHF) in rectangular channels, experiments were performed with FC-72 at 1.36 bar for channel heights of 2, 5, and 10 mm. Boiling heat transfer from a linear array of nine discrete heat sources simulating microelectronic chips was investigated for velocity and liquid s...

This study examines the single-phase and two-phase cooling performance of a hybrid micro-channel/micro-jet impingement cooling scheme using HFE 7100 as working fluid. This scheme consists of supplying coolant from a series of jets that deposit liquid into the micro-channels. A single-phase numerical scheme that utilizes the k–e turbulent model and a method for determining the extent of the lami...

This study investigates critical heat flux (CHF) for subcooled flow boiling of n-Perfluorohexane based on results pre-launch Earth-gravity Mission Sequence Tests (MSTs) the Flow Boiling and Condensation Experiment (FBCE), which was launched to International Space Station (ISS) in August 2021. CHF measurements were made a rectangular channel having 2.5 mm by 5 cross-section 114.6-mm long heated ...
