“…Thermal performances and their temperature profile during charging and discharging for two different fluids depend upon fluid temperature, wall temperature, ambient temperature and other parameters. A new type of NEPCM is fabricated by Chananipoor et al 66 using N‐dodecanol as core PCM and PMMA and GO as supporting material. The results obtained from the study revealed that latent heat of melting for average‐sized particles is 148.5 J/g.…”

This article reports detailed investigation of using different Phase Change Materials (PCM) in various designs of Thermal Energy Storage (TES) Devices: specifically, heat exchanger. The focus is on the performance analysis of different types of heat exchangers acting as TES having various PCMs which are substantially reviewed in this paper. The study highlights the difference in their geometry and performance output. Further, the importance of different performance enhancement methods with parametric study of different heat exchangers using PCM is described. From the detailed investigation, finally, it is realised that the different factors such as no. of outer tubes, no. of inner tubes, tube material selected, type of PCM, provision of an extended surface, use of different metal foams and nanoparticles, various types of composites, charging and discharging characteristics and packed and cascaded units are different heat transfer enhancement methods to improve the heat transfer. A novel kind of heat exchanger known as Webbed tube heat exchanger using PCM is discussed for an efficient TES unit. Further, a review of quantitative analysis of melting time, solidification time, charging and discharging time is discussed.

“…Slurries of mPCM (nPCM), as clearly demonstrated in experimental studies [59][60][61][62][63][64] and CFD simulations [65][66][67][68][69], are characterized by better effective storage of thermal energy [70][71][72][73] but also by convective heat transfer during the flow of heat-transfer fluid [74][75][76][77][78][79][80][81]. It should be noted, however, that replacing the pure liquid with a slurry with the addition of mPCM improves the heat-transfer coefficient, but it causes an increase in pressure drop.…”

The paper chronologically describes the results of research on the flow of micro-encapsulated PCM (mPCM) and nano-encapsulated PCM (nPCM) slurry in heat-transfer systems. The focus is on three thematic groups: mPCM (nPCM) slurry flow pressure drop; the friction factor in the laminar, transient, and turbulent flow of slurry in the channels; and the assessment of the effectiveness of using the mPCM (nPCM) slurry in the context of improving heat-transfer coefficients but with increased pumping power. It was found that the number of publications devoted to the above-mentioned topics is very limited compared to the research on the thermal and rheological properties of the mPCM (nPCM) slurry, which has resulted in the lack of systematized knowledge about the influence of slurry concentration, particle size, materials, etc., for example, on the friction factor. It was found that the use of the mPCM (nPCM) slurry in heat-transfer systems may be proper, provided that an appropriate and sufficiently high flow rate is ensured.

“…N/MPCMS consisting of encapsulated particles dispersed in the carrier fluid, mainly water and glycol, benefits from the advantages of both sensible and latent heat. In other words, a higher heat capacity is achieved for convective heat transfer that can be used in several industrial fields, including pumping active systems [7], refrigeration purposes [7], heat exchangers [8], heating [9] and solar energy [10].…”

Heat transfer fluids play a significant role in cooling or heating systems to maintain or obtain a particular temperature. A relatively novel concept is adding nano/microencapsulated phase change material (N/MPCM) to the carrier fluid to increase the heat capacity and improve the heat transfer rate. However, the applicability of using particles and their performance demand further investigations. In this study, a review of the recent progress has been made on using N/MPCM slurry as the working fluid is provided. The effects of particles' thermophysical properties, including size, concentration, melting point and enthalpy, on different performance indicators such as exergy, efficiency, pumping power and performance evaluation criterion are among the covered topics. Although the promising potentials of MPCM slurry have increased interest in this field, there are still significant research gaps in the literature that are suggested for future investigations.
