Summary

An equivalent volumetric enthalpy variation corresponding to the thermal field in the freezing or thawing zone is used. Results obtained from calculations applying this approach are compared with experimental measurements. Freezing-zone progression measurements were made in the course of three freezing experiments. In addition, 35 values for thawing time have been taken from the literature presenting experiments. The proposed method seems to be useful for many practical applications, particularly because it allows calculation of the freezing or thawing time without necessitating the use of empirical parameters in Plank's original equation.
