Solidification of aqueous binary solution on a vertical cooled plate with main flow

An experimental study of the transient solidification of an aqueous binary solution from a vertical cooled plate is reported in this paper. A copper plate of the flow duct, which has 50 mm×70 mm in cross-sectional dimension and 500 mm in length, was cooled uniformly. Ethylene-glycol solution was adopted as a testing liquid. The dependence of the plate wall temperature, the flow rate, the entry-liquid concentration, and the entry-liquid temperature on the solidification characteristics were extensively determined. The data reveal that the characteristics of the frozen layer at both the onset and the steady state could be favorably classified as a function of Reynolds number and the cooling temperature ratio. The correlation of the averaged frozen-layer thickness at the steady state was determined.
