Experimental investigation and modelling of a laboratory-scale latent heat storage with cylindrical PCM capsules

Abstract Heat storage efficiency is required to maximize the potential of combined heat and power generation or renewable energy sources for heating. Using a phase change material (PCM) could be an attractive choice in several instances. Commercially available paraffin-based PCM was investigated usi...
