WebConversely, when the material is melted, an equal amount of energy is absorbed from the immediate environment as it changes from solid to liquid. This property of PCMs can be used in a number of ways, such as thermal energy storage whereby heat or coolness can be stored from one process or period in time, and used at a later date or different location. WebOne way to study the dynamics of first order phase transitions is through solving the Stefan problem. The goal of this work is to develop a framework that allows researchers to predict the behaviour
