Suppression of Ice Formation around a Cooled Tube Using Liquid-Fluidized Bed

(Further Report : Evaluation of Ice Layer as Thermal Resistance)

Abstract

An experimental study was performed on ice formation around a brine-cooled tube embedded horizontally in a liquid-fluidized bed. It was found that the ice layer thickness evaluated from thermal resistance, equivalent thickness, is thinner than the actual average thickness, and that the ratio of the equivalent to the average thickness depends on a non-dimensional parameter consisted of Biot number and cooling temperature ratio for liquid single-phase flow, and additionally of the Archimedes number for liquid fluidized bed.
