“…Passive methods can be implemented by the use of heat pipes 10 and phase-change materials (PCMs). 11,12 Meanwhile, the use of PCM-based methods provides a great opportunity in the thermal management of a battery pack. 13 These materials provide a very uniform temperature distribution in the battery pack, as well as controlling the maximum battery temperature.…”

The thermal management system of a Lithium-ion battery consisting of phasechange material (PCM) is considered in this study. The batteries are covered by a large volume of PCM. A 18650 battery is used in this numerical investigation as a case study and all achievements are implemented on it. The battery thermal management system (BTMS) parameters during discharge-restcharge-rest cycles are concerned to understand PCM behavior and battery resilience in the long run. The battery is placed adjacent to various PCMs and is charged and discharged at different rates. Results show that the paraffin wax has the worst performance, and hydrate salt and capric acid have the best performance. Furthermore, the use of polyethylene glycol as PCM improves the performance of the BTMS. Meanwhile, the composite of nano-graphite and PCM would increase a reasonable effect on the BTMS functionality.

“…PCMs are capable of absorbing and releasing heat energy as they experience phase change process from solid to liquid, and vice versa [17]. PCMs are used in several fields such as energy conservation [18], exchangers [19] and electronic devices [20]. Several researchers used the PCM in different engineering systems for sustainable development.…”

Latent Heat Phase Change Heat Transfer of a Nanoliquid with Nano–Encapsulated Phase Change Materials in a Wavy-Wall Enclosure with an Active Rotating Cylinder

A Nano-Encapsulated Phase-Change Material (NEPCM) suspension is made of nanoparticles containing a Phase Change Material in their core and dispersed in a fluid. These particles can contribute to thermal energy storage and heat transfer by their latent heat of phase change as moving with the host fluid. Thus, such novel nanoliquids are promising for applications in waste heat recovery and thermal energy storage systems. In the present research, the mixed convection of NEPCM suspensions was addressed in a wavy wall cavity containing a rotating solid cylinder. As the nanoparticles move with the liquid, they undergo a phase change and transfer the latent heat. The phase change of nanoparticles was considered as temperature-dependent heat capacity. The governing equations of mass, momentum, and energy conservation were presented as partial differential equations. Then, the governing equations were converted to a non-dimensional form to generalize the solution, and solved by the finite element method. The influence of control parameters such as volume concentration of nanoparticles, fusion temperature of nanoparticles, Stefan number, wall undulations number, and as well as the cylinder size, angular rotation, and thermal conductivities was addressed on the heat transfer in the enclosure. The wall undulation number induces a remarkable change in the Nusselt number. There are optimum fusion temperatures for nanoparticles, which could maximize the heat transfer rate. The increase of the latent heat of nanoparticles (a decline of Stefan number) boosts the heat transfer advantage of employing the phase change particles.

“…This type of energy storage unit has been adopted in electronic cooling and ventilation applications [2] [3]. With phase change materials, a significant temperature reduction in the operating temperature of electronic devices can be achieved, which significantly improves their performance and enhances stability [4]. However, the low thermal conductivity limits the application of phase change materials [5] [6].…”
