The comparison of liquid fractions during NePCM solidification at different time intervals (t = 100 s and 500 s) was conducted for Cu volume fractions of ∅ = 0%, 10%, and 20%. In this analysis, the red color represents the liquid region, while the blue color indicates the solid region (Khodadadi & Hosseinizadeh, 2007).

... nanoparticles significantly influence the phase change behavior of NEPCM due to their high thermal conductivity. Figure 3 illustrates that increasing the volume fraction of Cu nanoparticles from 0% to 20%, and from 0% to 5% in a ring-shaped NEPCM, enhances thermal conductivity and heat transfer rates, thereby reducing the overall solidification time. Elbahjaoui et al. (Elbahjaoui & El Qarnia, 2017) (Khodadadi & Hosseinizadeh, 2007). ...

... instance, a study examining the thermal conductivity of pure paraffin PCM and paraffin PCM infused with CuO nanoparticles at varying temperatures highlighted a significant increase in thermal conductivity for the nanoparticle-enhanced PCM. The data, as illustrated in Figure 3, demonstrated that the inclusion of CuO nanoparticles markedly improved the material's ability to conduct heat. Additionally, increasing the concentration of nanoparticles further enhanced the thermal conductivity, indicating a direct correlation between nanoparticle volume fraction and heat transfer performance. ...
