Experimental study on ice slurry generations with sodium chloride solution-based concentrations and flow-rates

Research output: Contribution to journalArticlepeer-review

Abstract

This study was aimed at observing the effects of factors such as flow rates and concentrations on the rate of temperature reduction, the degree of supercooling, and ice fractions. The study was conducted with various flow rates amounting to 6.2, 7.9, 9.5, and 11.2 L/min, and various concentrations amounting to 3%, 4%, and 5% using NaCl solution. Ice slurry generators were expected to produce high ice fraction with minimum energy consumption. In the cooling process, the solution temperature dropped below the freezing point of pure water until it hit the minimum value called the degree of supercooling. The flow rate of 7.9 L / min and the concentration of 3% is the most optimum value among the other variations for the purpose of the highest temperature reduction speed and the lowest degree of supercooling. The most optimum flow rate among the other variations to produce the highest ice fraction in the fastest time is also 7.9 L / min.
