Packed bed thermal energy storage: A simplified experimentally

A low void fraction in the bed will lead to a smaller storage vessel for a given amount of energy to be stored, but the pressure drop is increased. Similarly, smaller bead sizes minimize intra-particle temperature gradients (assuming sufficiently high thermal conductivity of the storage media), but also lead to a higher pressure drop.

Melting and solidification analysis of phase change material-metal

At t = 1000s, total latent heat stored in PCM storage system with and without void are found to be 506.9 kJ/m 2 and 644.2 kJ/m 2 and total energy stored are found to be 551.3 kJ/m 2 and 714 kJ/m 2, respectively. This indicates that energy stored in the PCM with void is lower compared to case that does not include void in the model.
