A note on the two models of ice growth velocity in aqueous solutions derived from an irreversible thermodynamics analysis and the conventional heat and mass transfer theory

In this note, the physical and chemical aspects of a mathematical model of ice growth velocity, as derived recently from irreversible thermodynamics theory (IT), have been compared with a model obtained by applying the conventional heat and mass transfer and thermodynamics theory (CHMT). The comparison shows that the IT model involves the heat flux equation that does not contain an energy balance about the ice-liquid interface and therefore ignores the temperature gradient on the ice sine of the interface. This may lead erroneously to predictions of practical consequences which conflict with the CHMT model. (C) 1997 Elsevier Science Limited.
