Enhanced melting in geometries suitable for thermal energy storage Academic Article uri icon


  • ABSTRACT Phase-change materials (PCMs) are able to store large amounts of heat but have low thermal conductivity. Heat transfer in PCMs can be enhanced by fins that enlarge the heat transfer area. However, when the PCM melts during the storage unit charging, a layer of liquid is growing at the fins creating an increasing thermal resistance that impedes the process. The present work aims to demonstrate that charging of a latent-heat thermal storage unit may be considerably affected by achieving a so-called close-contact melting …
