“…They determined that the cascade PCM thermal storage system outperforms the single PCM thermal storage system. Sharaf et al 18 evaluated a passive cooling technology that combines an aluminum metal foam (AMF) and PCM to regulate the temperature of a photovoltaic (PV) system (PV-PCM/AFM). The results indicated that the power produced by the PV-PCM/AFM system was 1.85 percent, 3.38 percent, and 4.14 percent higher than that of conventional PV during December, January, and February respectively.Heat energy storage systems offer the benefits of high energy storage efficiency and consistent temperature due to the use of phase change material (PCM); however, its disadvantage is that thermal energy storage takes longer to complete due to the material poor thermal conductivity.…”

The current paper discusses the numerical simulation results of the NePCM melting process inside an annulus thermal storage system. The TES system consists of a wavy shell wall and a cylindrical tube equipped with three fins. The enthalpy-porosity method was utilized to address the transient behavior of the melting process, while the Galerkin FE technique was used to solve the system governing equations. The results were displayed for different inner tube positions (right-left–up and down), inner cylinder rotation angle (0 ≤ α ≤ 3π/2), and the nano-additives concentration (0 ≤ ϕ ≤ 0.04). The findings indicated that high values of nano-additives concentration (0.4), bigger values of tube rotation angle (3π/2), and location of the tube at the lower position accelerated the NePCM melting process.

A solar panel will be exposed to sunlight when in use, which causes its temperature to increase. The performance of power production will be impacted if the solar panel's temperature conditions are too hot. High-temperature solar panels can reduce the amount of electrical energy generated. To prevent the temperature of the solar panels from rising too much, a cooling system is required. The proposed solution of this research is a cooling system for solar panels that makes use of heat transfer through water. The solar panels tested in this study have a tilt angle of 20 degrees. The cooling device has dimensions of 400 mm length, 278 mm width, and 20 mm height, with a wavy-type vortex generator positioned in the cooling device mounted on the underside of the solar panel. As a result of the heat flux applied to the top surface of the solar panel, it causes an increase in temperature. The resulting voltage and electric current are reduced. Computational simulations were carried out to determine the performance of the type of vortex generator used. At a cooling water flow rate of 200–600 ml/min, heat transfer with a vortex generator type B works optimally.

“…The greater heat transfer rates (both heat absorption and heat dissipation) are important for applications such as thermal energy storage 8 and cooling for photovoltaic systems. 9 In this regard, developments of paraffin based PCM by mixing with inorganic nanoparticles have been explored, because the thermal conductivity of the inorganic nanoparticles are greater than that of the organic-based PCM. The inorganic fillers used include multiwall carbon nanotube (MWCMT) 10 and metal oxides such as Al 2 O 3 11 and copper oxide nanoparticles (CuO).…”

This research work concerns the development of phase change materials based on poly(ethylene terephthalate) (PET) mixed with vanadium dioxide particles (VO2). Monoclinic VO2 particles were synthesized via a hydrothermal process followed by modification of the particle surface with a silane coupling agent, namely 3‐(aminopropyl) triethoxysilane (APTES). After that, the metal oxide particles were mixed with PET flakes, derived from used PET bottles, in an internal mixer. In this study, the effects of surface modification and concentrations of VO2 particles on thermomechanical and optical properties of the composites were investigated. From the DSC results, it was found that the percentage crystallinity of PET increased after loading with VO2. This indicates that VO2 can act as a nucleating agent inducing the crystallization of the PET chains. From the scanning electron microscopy with energy dispersive X‐ray spectroscopy (SEM–EDX) images, better dispersion of VO2 particles in the PET matrix was noticed when the surface‐modified VO2 particles were used as a replacement for the normal VO2 particles. This contributed to the greater percentage of visible light transmittance through the composite sheets. Thermogravimetric analysis (TGA) profiles of both PET and PET/VO2 specimens are similar, indicating that the VO2 did not accelerate the thermal decomposition of the PET. When the specimens were exposed to an IR lamp, it was found that the temperature behind the PET/VO2 sheets dropped when compared to that of the neat PET sheets. Some shrinkage and deformation of the PET/VO2 specimens were also noticed. The higher the VO2 loading, the greater the deformation. The effect was ascribed to the fact that the actual temperature was above the critical transition temperature of VO2. Consequently, the NIR transmittance was suppressed at the expense of the greater NIR absorbance by the VO2 phase in the composites. Finally, when the specimens were exposed to solar irradiation at ambient temperature, the temperature underneath the PET/VO2 specimens became greater than that of the control specimen (the neat PET). The result was discussed in the light of the emissivity of VO2 at ambient temperature, which is considerably low. Overall, this study demonstrates that PET/VO2 can exhibit both cooling and warming effects, depending on the ambient temperature in relation to the critical transition temperature (Tc) of VO2.
