The effect of natural convection on ice crystal growth rates in salt solutions

Abstract

AbstractMany measurements of ice growth rates in NaCl solutions have been made to determine the role of natural convection in the control of such growth rates. The results of two analyses are presented. In one, only thermal natural convection is treated for growth in pure water. The second treats the simultaneous effects of both mass and thermal natural convection in salt solutions. This second analysis correctly predicts higher ice growth rates in dilute salt solutions than in pure water.
