A cell model of moisture freeze-up in a plane heat conducting wall
A cell non-linear mathematical model of heat transfer through a plane wall containing moisture undergoing the phase transformation “freeze-up – thaw” is proposed. The model is built on the basis of a universal computational algorithm that is based on the mathematical tool of Markov chains theory and allows calculating transient and steady-state heat processes in the wall taking into account freeze-up and thaw of moisture. Examples of calculation of frost penetration front at various external conditions are presented.
