“…The researchers usually use Nusselt number to study the heat transfer characteristics, and Reynolds number and friction factor to study the hydrodynamic characteristics. To investigate the heat transfer properties of N/MPCS, Roy and Avanic [84] and Chen et al [69] proposed the Stephen number to denote the ratio of the sensible heat to latent heat in the phase change process. To investigate the hydrodynamic properties of N/MPCS owing to the higher viscosity in comparison with base fluid, Rajabifar et al [62,63] demonstrated Euler number variation with NPCM concentration at different inlet velocities, and Euler number was defined as a nondimensional number related to the ratio of pressure drop of the system and squared Reynolds number.…”

“…For pressure drop correlations, if the suspended particle size is very small and their volume concentrations are relatively low (less than 20-25%), the Newtonian flow assumption is valid for MPCS, which has been carefully discussed by Charunyakorn et al [87], Roy and Avanic [84] and Wang et al [83,86]. The classical friction factors f were recommended for pressure drop calculation.…”

Mini/microchannel heat sinks are currently widely used in a variety of thermal and energy applications with the advantages of compactness, light weight and higher heat transfer performance. In order to further improve the performance of such heat sink, many recent studies have introduced the nano/microencapsulated phase change slurry (N/MPCS) as the working fluid due to their high storage capacity during phase change. This paper concerns the channel with hydraulic diameter from 10 μm to 3 mm, covering the range of microchannel and minichannel. Firstly, the existed review works relate to mini/microchannel heat sinks are summarized, with topics covering manufacturing processes and geometric designs, thermal and hydrodynamic performance with different working fluids, and their typical and potential applications. Then, the N/MPCS used in mini/microchannels from experimental and numerical simulation works are discussed, with focuses placed on the base fluid, core and shell materials, and thermophysical properties of slurry. Next, the local, average and overall heat transfer and hydrodynamic characteristics of mini/microchannel heat sinks with N/MPCS flowing inside are reviewed and analyzed, considering different flow conditions, material and dimension of test section, and composition and fraction of such slurry. Finally, the proposed heat transfer and pressure drop correlations in this research field are evaluated. The purpose of this review

Micro-encapsulated Phase Change Material (MPCM) slurries, acting as the heat transfer fluids or thermal storage mediums, have gained applications in various building thermal energy systems, significantly enhancing their energy efficiency and operational performance. This paper presents a review of research on MPCM slurries and their building applications. The research collects information on the currently available MPCM particles and shells, studies of the physical, structural and thermal stability, and rheological properties of MPCM slurries, and identification/determination of the critical parameters and dimensionless numbers relating to the MPCM slurries' heat transfer. The research suggests possible approaches for enhancing the heat transfer between a MPCM slurry and its surroundings, while several controversial phenomena and potential causes were also investigated. Furthermore, the research presents mathematical correlations established between different thermal and physical parameters relating to the MPCM slurries, and introduces a number of practical applications of the MPCM slurries in building thermal energy systems. Based on such extensive review and analyses, the research will help in identifying the current status, potential problems in existence, and future directions in research, development and practical application of MPCM slurries. It will also promote the development and application of cost-effective and energy-efficient PCM materials and thus contribute to achieving the UK and international targets in energy saving and carbon emission reductions in the building sector and beyond.
