Abstract
An experiment is reported on heat transfer from an OFHC flat plate to a bath of subcooled liquid helium. This work was undertaken because of the technological interest in supermagnet cooling and because there has been very little previous heat transfer work with subcooled helium. The only comparable research was done by Tsuruga and Endoh [1], who worked at 1 atm pressure. On the other hand, heat transfer to saturated liquid helium and to supercritical helium has been extensively studied [1–19]. In this study, helium pressure is changed from 0.36 to 1.97 atm and its temperature is changed from 2.5 K to the saturation temperature corresponding to the helium pressure.
