Abstract
It is useful to be able to predict the growth of a mushy region accurately for designing a harvest-type ice storage system. The discussion here is focused on non-isotropic thermal conductivity and the effects of non-equilibrium conditions, which are not considered in conventional models. Because the non-isotropic structure depends on subcooled conditions, it is important to consider these effects on the growth of a mushy region. In this study, some ideas are proposed for considering the non-isotropic conductivity which reflects the inner structure. When the subcooling degree when nucleation starts is given, it is possible to consider the effects of subcooling on growth of a mushy region by applying the Universal Law and Fourier’s Law to changing the crystal growth mode.
