Abstract
Abstract This experimental study presents subcooled flow boiling of an engineering fluid - HFE-7000 - downstream a single pin fin in a microchannel. A liquid secondary jet was introduced into the flow to examine its merits pertinent to heat transfer enhancement. It was found that for HFE-7000 high wall superheats (ΔT(sat,ONB)∼40°C) were required for the onset of nucleate boiling (ONB). Once boiling started, nucleate boiling dominated. Heat transfer coefficient increased monotonically with heat flux, independent of mass flux and jet injections. Secondary flow injection, which was previously found to be an affective single phase heat transfer enhancement technique, showed limited potential for fully developed nucleate boiling.
