Latent heat thermal energy storage (LHTES) uses phase change materials (PCMs) to store and release heat, and can effectively address the mismatch between energy supply and demand. However, it suffers from low thermal conductivity and the leakage problem. One of the solutions is integrating porous supports and PCMs to fabricate shape-stabilized phase change materials (ss-PCMs). The phase change heat transfer in porous ss-PCMs is of fundamental importance for determining thermalfluidic behaviours and evaluating LHTES system performance. This paper reviews the Highlights: 1. The recent advances in experimental and numerical investigations on phase change heat transfer in porous ss-PCMs are reviewed. 2. Paraffin and metal foams are the mostly used PCM and porous support respectively in the experimental studies. 3. Compared to REV-scale simulation, the pore-scale simulation can provide extra flow and heat transfer characteristics in pores. 4. There exists a research gap between phase change heat transfer and material preparation.

“…Many recent attempts have been made for thermal conductivity enhancement of PCM. This could be achieved by different metal foams addition resulting in increased heat discharging and charging rates in thermal energy storage as observed by [7][8][9][10][11].

Abstract. Phase change materials (PCMs) are energy storage materials which can be used for maintaining a controlled thermal environment for various applications in earth and space. PCMs are used in advanced technologies in aerospace cooling applications like heat exchangers and heat pipes for re-entry vehicles and spacecraft. Paraffin is a phase change material (PCM) commonly used for energy storage-related applications. Paraffin wax exhibits slow thermal response due to low thermal conductivity value (~0.2 W/m K for most paraffin waxes). In the present work, an attempt is made to fabricate a composite PCM using graphite powder. Such a composite material has enhanced thermal conductivity along with reduced melting period which are desirable properties of a PCM during solid to liquid phase change process. The reduction in melting period is indicated by the difference in change in temperature measured by the thermocouples during a specified time. The temperature variation and solid-liquid interface formation during the melting process are experimentally studied. The results showed that composite graphite powder with paraffin can improve the total phase transition time.

Present paper reports the thermal performance of various phase change material (PCM)-based heat sinks during melting process for cooling of portable electronic devices through experimental investigations. Heat sink configurations include unfinned with pure PCM, finned with pure PCM, unfinned with metallic foam (MF)-PCM composite, and finned with MF-PCM composite. Paraffin wax is used as PCM, and tests have been carried out for various input heat flux values (1.3, 2.0, and 2.7 kW/m 2) at different volume fractions of PCM (0, 0.50, 0.86, and 1). The effect of various parameters such as PCM volume fraction, heat sink type, and heat flux on the stretching of operating time to achieve a set point temperature (SPT) is studied. Results obtained from the current experimental investigation are compared with the existing test results. Also, unfinned heat sink without and with PCM is used for baseline comparison. The evolution and propagation of melt front inside the heat sink are studied through photographic observation. The enhancement in operating time is found to vary with the SPT and heat flux values. MF-PCM-based heat sinks are more advantageous for higher value of input heat flux (2.0 and 2.7 kW/m 2). For q 00 = 1.3 and 2.0 kW/m 2 , four-finned MF-PCM-based heat sink exhibits better performance; while three-finned MF-PCM-based heat sink shows best performance at q 00 = 2.7 kW/m 2. The highest enhancement ratio of 2.97 is obtained at 1.3 and 2.7 kW/m 2 for four-finned MF-PCM heat sink and three-finned MF-PCM heat sink, respectively. Also, threefinned heat sink provides higher heat transfer rate and highest thermal conductance at q 00 = 2.7 kW/m 2.
