Abstract
An experimental and analytical study was performed to investigate the freezing characteristics of an aqueous binary solution. Ethylene glycol solutions of 5, 10, 30, 40, and 50 wt% in concentration were utilized as testing solutions, and experiments were carried out for various initial and cooling temperatures. The effects of concentration and cooling temperature on the frozen layer of solution formed on a horizontal plate were examined extensively. It was found that the frozen layer became a mushy dendritic ice layer, except for the case of both high concentration and quite rapid or slow freezing, and that the analytical were in good agreement with the experimental ones for the dendritic ice layer.
