Numerical solution of multiple front phase change problems for modeling ice thermal storage systems
Phase change problems with multiple fronts in cylindrical systems, which arise in ice-on-pipe brine thermal energy storage systems, are investigated in this study. Two numerical methods, the boundary element method ( BEM ) and the thermal network method ( TNM ), are developed to solve the multiple …

Phase-field Modeling of Phase Change Phenomena
The phase-field method has become a popular numerical tool for moving boundary problems in recent years. In this method, the interface is intrinsically diffuse and stores a mixing energy that is equivalent to surface tension. The major advantage of this method is its energy formulation which makes …

Dynamical Phase-Change Phenomena
Matter on earth exists mostly in three different phases of solid, liquid, and gas. With extreme amounts of energy, temperature, or pressure, a matter can be changed between the phases. Six different types of phase-change phenomena are possible: freezing (the substance changes from a liquid to a …
