Abstract

A liquid ice is useful as a cold heat storage material. Heat transfer experiments were carried out for continuous formation of liquid ice in the vertical pipe where water is chilled by immiscible coolant. Experimental results showed that the direct contact of water and coolant in the vertical pipe was practicable for continuous formation of the liquid ice. As a result, or empirical correlation of capacity coefficient of heat transfer was obtained. The calculated results which were estimated by using the correlation were in good agreement with experimental results. Within the experimental range, it was made out that heat transfer efficiency and mass fraction of ice were correlated with the ratio of water and coolant mass flow rate within the experimental condition.
