“…At present, the methods enhancing the heat dissipation of PCM can be mainly divided into two categories. One is increasing the thermal conductivity of PCM by adding high thermal conductive particles or fillers to fabricate composite PCM, such as paraffin wax/expanded graphite (paraffin wax/EG) [5,6], paraffin wax/metal foams [7][8][9], and paraffin wax/nano-materials [10,11]. The other one is placing high thermal conductivity inserts into PCM through structure design, such as aluminum fins [12,13], capillary driven heat pipe, gravity assisted heat pipe (GHP) [14][15][16][17][18][19], and others.…”

Summary The electronic industry is increasingly investigating different approaches for the cooling of electronic equipment. The use of bulk phase change materials is also a promising approach for energy storage. The introduction of microencapsulated phase change materials combined with nanofluids can be beneficial. The combined use of a nanofluid and a metallic porous material can be used to mitigate problems resulting from small thermal conductivity. This study investigated a ternary mixture of water with a nanofluid and a microencapsulated phase change material in a porous medium. The model was previously validated with experimental data using a 0.5%vol concentration nanofluid in water. The results revealed that heat storage capability can be achieved as long as the microencapsulated phase change materials, which consists of encapsulated eicosane, is at a concentration of 20%. Because the melting temperature of microencapsulated phase change materials is approximately 36°C, energy storage at a low flow rate and heat flux is recommended.

“…A numerical investigation on the thermal behaviour of sodium nitrate (NaNO 3 ) as a PCM was conducted using the commercial computational fluid dynamics (CFD) software, Fluent . Fleming et al compared the thermal performance of two shell‐and‐tube LHS units, with one composed of aluminium foam. The experimental results showed that the foam significantly increased the heat transfer during both melting and solidification in terms of the overall heat transfer coefficient.…”

Summary Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used later for heating and cooling applications and for power generation. TES has recently attracted increasing interest to thermal applications such as space and water heating, waste heat utilisation, cooling, and air conditioning. Phase change materials (PCMs) used for the storage of thermal energy as latent heat are special types of advanced materials that substantially contribute to the efficient use and conservation of waste heat and solar energy. This paper provides a comprehensive review on the development of latent heat storage (LHS) systems focused on heat transfer and enhancement techniques employed in PCMs to effectively charge and discharge latent heat energy, and the formulation of the phase change problem. The main categories of PCMs are classified and briefly described, and heat transfer enhancement technologies, namely dispersion of low‐density materials, use of porous materials, metal matrices and encapsulation, incorporation of extended surfaces and fins, utilisation of heat pipes, cascaded storage, and direct heat transfer techniques, are also discussed in detail. Additionally, a two‐dimensional heat transfer simulation model of an LHS system is developed using the control volume technique to solve the phase change problem. Furthermore, a three‐dimensional numerical simulation model of an LHS is built to investigate the quasi‐steady state and transient heat transfer in PCMs. Finally, several future research directions are provided.
