Experimental study on melting/solidification characteristics of a paraffin as PCM
TL;DR: In this article, the melting and solidification processes of paraffin as a phase change material (PCM) in a tube in shell heat exchanger system were investigated. But the authors focused on the possibility of the heat transfer enhancement in the heat storage geometry, which is achieved by tilting the outer surface of the storage container.
