ABSTRACT
A model for simulating the formation of ice lenses during freezing of unconfined uniform porous media is presented. The main notions of the model are that generation and jump are dependent on the freezing rate, and that growth is dependent on supercooling. The critical freezing rate is assumed to vary with changes in the number of particles near the ice lens due to the growth of the ice lens. The proposed model was computed for the unidirectional freezing of a porous medium consisting of 10 μm-diameter glass particles. The numerical results show that this model can represent the formation of intermittent layers of ice lenses in the porous medium. This model can be applied to ice formation in unconfined water-soaked porous media.
