Résumé

The authors propose the use of a low concentration aqueous solution as phase change material instead of pure water. If an aqueous solution with low concentration is used, even when a large amount of solution (aqueous ethylene glycol in the study) is solidified and bridging of ice developed around cold tubes occurs, the pressure increase could be prevented by the existence of a continuous liquid phase in the solid-liquid two-phase layer (mushy layer) which opens to an air gap at the top of a vessel. Therefore, one can continue to solidify an aqueous solution after bridging, achieving a high ice packing factor (IPF). Experiments using small-scale test cells have been conducted and then the authors performed experiments using a large vessel with a nearly practical size. It was seen that a large pressure increase is prevented and IPF obtained is much greater than 0.65 using pure water for which the solidification must be stopped before the bridging.
