Ma, Fei | Zhang, Peng
Phase change slurry (PCS) as a solid-liquid two-phase fluid, comprising phase change material (PCM) particles and carrying fluid, shows significant potential in heat transfer and thermal energy storage. Furthermore, it displays better heat transfer and energy transport performances than the single-phase fluid due to large heat capacity of PCM particle. The shellless PCSs include 1-component slurry and clathrate hydrate slurry (CHS), in which there is mass transfer between solid particles and carrying fluid during phase change. A comprehensive two-part review on the studies of the shellless PCSs is summarized in the present study from different aspects. The preparations, properties and applications of the shellless PCSs are summarized in the first part. This paper is the second part of the review, focusing on the thermo-fluidic characteristics of the shellless PCSs. The flow pattern, rheological behavior, pressure drop and heat transfer performance, etc., of the PCSs are comprehensively reviewed in this part.
