Comparison of phase change slurries: physicochemical and thermal properties

Phase change slurries (PCS) consist on a carrier fluid binary system, where water is mostly used as continuous phase and micro-encapsulated phase change materials (MPCM) are used as dispersed phase. PCS are used in Thermal Energy Storage (TES) for building applications, combining the latent heat cap...
