An Experimental Study On Solidification Of Pure Water Or A Dilute Salt Solution In A Horizontal Copper Tube, Hwa-Chong Tien, Sih-Li Chen, Bing-Shiang Yang

Journal of Marine Science and Technology

Solidification of pure water and NaCl-HO solutions in a copper tube is investigated experimentally. The morphology and growth of the two phase region is observed photographically, In the experiments of NaCl-H2O solutions, the salt concentrations in the solutions are smaller than the concentration at the eutectic point. The coolant temperature is higher than the eutectic temperature. The supercooling phenomenon and the effects of the coolant temperature, initial temperature of water or NaCl-HzO solution, and the concentrations of the solutions are studied in detail. In addition to the photographs, results presented also nclude the temperature responses of water and NaCl-H2O solutions …
