“…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.

“…The heat transfer coefficient of jet impingement cooling increases by 50%-70% after the working fluid is loaded with EPCM, and the capsules can maintain complete structure after multiple cycles (Wu et al, 2011). However, a high pressure drop and heat transfer resistance of EPCM were also observed (Wan et al, 2021). What is more, the PCMS exhibit greater cooling efficiency than singlephase coolants only when the jet inlet temperature is in a certain range related to the PCM melting point.…”

“…Adding encapsulated phase change materials (EPCMs) into a base working fluid forms a PCM slurry (PCMS), which circumvents the defects of PCM and offers a feasible approach to thermal management. The invariant temperature during the phase change makes PCMS more competitive than conventional coolants in many cooling technologies, such as microchannel (Wang et al, 2016), jet and spray cooling (Wan et al, 2021), heat pipes (Heydarian et al, 2019), etc. In particular, when the heat flux is high, up to a 40% decrement in the internal wall temperature, a 50% increase in heat transfer coefficient (Sabbah et al, 2012), and a 67.5% decrement in the pumping power (Chen et al, 2008) can be achieved by the application of EPCM.…”

Miniaturisation in avionics, electronics, and medical appliances has led to demands for rapid heat dissipation techniques. The spray cooling technique has gained importance recently due to its advantage over other cooling methods. Parameters affecting heat transfer mechanisms during spray cooling are contemplated. This review presents different heat transfer parameters and their effect on spray cooling by analysis from past studies. Heat transfer surface modifications and different coolant variations to enhance heat transfer effectiveness are also reviewed. Apart from high heat flux having more applications, low heat flux studies have also grabbed the researchers to find solutions with a temperature range lower than 250˚C. Therefore, the upcoming spray cooling technology will have broad applications that will contribute to the maximum efficiency of the heat removal rate.
