Experimental Analysis of Solidification and Remelting of Brine Solution Over a Cryocooled Sphere

Abstract

The Solidification and remelting of brine solution having different concentration over a cryocooled steel sphere is studied experimentally. Liquid nitrogen is used to chill the sphere at cryogenic temperature up to 77 K. Experiments are conducted to show the variation in thickness of ice formation at the outer surface of cryocooled solid sphere for different concentrations, locations and time intervals. It was observed that ice formed on the outer periphery of cryocooled sphere is a function of NaCl concentration in the solution. As the concentration of solution increases, total time (solidification as well as melting) and thickness of ice is decreased. Melting pattern of ice is also reported for different concentrations.
