“…They found that the cooling performance of the MPCS strongly depended on the mass flow rate and the MPCS mass concentration. The 5 % slurry always showed a better cooling performance, which were same as Choi and Cho's study [146]. They also concluded that the slurry with higher mass concentration was more effective only at low mass flow rate; in contrast, at higher mass flow rates they showed a less effective cooling performance than water.…”

“…Choi and Cho [146] investigated the effect of a commercial paraffin with melting temperature of 43.6 °C on heat transfer enhancement in a multichip application. The results showed that the paraffin slurry with a mass fraction of 5 % showed the most efficient cooling performance when the heat transfer and the pressure drop in the test section was considered simultaneously.…”

The use of latent heat storage, microencapsulated phase change materials (MEPCMs), is one of the most efficient ways of storing thermal energy and it has received a growing attention in the past decade. However, there is no complete overview of its utilisation in thermal energy storage systems, and the information is widely spread in the literature. In this paper, a comprehensive review has been carried out for MEPCMs. Four aspects have been the focus of this review: fabrication and characterization of MEPCMs, applications of MEPCMs to the textile and building, fundamental properties of microencapsulated phase change material slurry (MPCS) and application of MPCS to the thermal energy storage system. Over 140 recent publications are referenced in this paper.

“…Previous investigations showed that MEPCMs can enhance convective heat transfer with appreciable reduction in mass flow rate and pumping power [3][4][5][6][7][8][9] . Kasza and Chen [3] estimated that the heat transfer coefficient could be increased up to three times using MEPCM suspensions, and MEPCM suspensions helped to reduce the source to sink temperature difference significantly.…”

Flow frictional characteristics of microencapsulated phase change material suspensions flowing through rectangular minichannels

et al. 2006

An experimental investigation was conducted on the laminar flow frictional characteristics of suspensions with microencapsulated phase change material (MEPCM) in water flowing through rectangular copper minichannels. The MEPCM was provided at an average particle size of 4.97 μm, and was mixed with distilled water to form suspensions with various mass concentrations ranging from 0 to 20%. The experiment was performed to explore the effect of MEPCM mass concentration on friction factor and pressure drop in the minichannels. The Reynolds number ranged from 200 to 2000 to provide laminar and transitional flows. It was found that the experimental data for the suspensions with 0 and 5% concentration agree well with the existing theoretical data for an incompressible, fully developed, laminar Newtonian flow. For the suspensions with mass concentrations higher than 10%, there is an obvious increase in friction factor and pressure drop in comparison with laminar Newtonian flow.

“…[7] In particular the thermal shielding of electronic devices becomes increasingly important since the large integration density makes high performance integrated circuits more sensitive to rapid temperature changes. [8] In the field of construction engineering PCMs have been proposed for the generation of thermal insulating concrete [9] and waste energy recycling for air conditioning systems. [10] Consumer products like protective clothing, [11] fabrics, [12] and textiles with PCM properties recently appeared on the market.…”

Applicability of Frozen Gels from Ultra High Molecular Weight Polyethylene and Paraffin Waxes as Shape Persistent Solid/Liquid Phase Change Materials

Ultra high molecular weight polyethylene (UHMW‐PE) physically gels molten paraffin waxes (PW) at concentrations exceeding 0.5 wt.‐%. In the composites the paraffin wax crystallises without destruction of the UHME‐PE gel network. Above the melting transition of the paraffin compound the capillary forces prevent the liquid wax from free flow. The composites can be processed by melt extrusion, and injection moulding above the melting temperature of the gel at 116 °C. The thermal and mechanical properties of these UHMW‐PE/paraffin composites have been characterised regarding their applicability as shape persistent phase change materials (PCM). The UHMW‐PE/PW gels can store, and release enthalpies up to 200 J/g at the melting temperature of the PW. In the gel state the liquid alkane can leave the gel when in direct contact to porous materials, and the gels mechanical strength are lower than that of standard polymers. These drawbacks are proposed to overcome by formation of PCM/polymer, or PCM/metal laminates.Schematic cross section of a proposed PCM laminate consisting of a polymer top‐ and bottom layer enclosing the UHMW‐PE/paraffin gel.magnified imageSchematic cross section of a proposed PCM laminate consisting of a polymer top‐ and bottom layer enclosing the UHMW‐PE/paraffin gel.
