AbstractAbstract
[en] An experimental program was established to improve low-temperature boiling heat transfer on a vertically-oriented surface in a heat pipe evaporator. The heat pipe was conceived as a passive decay heat rejection system (DHRS) in the SLOWPOKE 10 MWth pool reactor. Results from the test program were correlated with the Rohsenow dimensionless pool boiling equation, which worked well despite the vertical orientation of the heat transfer surface. The boiling heat transfer was improved by wrapping a Teflon-coated wire around the heat transfer surface. A simple model of the DHRS evaporator showed the Teflon wire-wrap could increase the DHRS heat removal by 11 to 19%. This paper describes the test apparatus, results and predicted improvements in the DHRS heat transfer capability. (Author) 10 refs., 13 figs., tab
