Using statistical analysis to create a new database of Nanofluids specific heat capacity

---

Publication Highlights

1. By adding nanoparticles, inorganic base fluids show higher enhancements than organic base fluids. Molten salts show a higher potential to enhance their Cp. In contrast, water-based nanofluids show low enhancements and a Cp worsening in general trends.
2. Temperature, concentration, and NPs size show a similar influence in the Cp value of nanofluids.
3. Metal oxides nanoparticles are the best candidates for Cp enhancements and metallic nanoparticles the worst ones.
4. The results show and optimal relationship between nanoparticles concentration and size: (concentration (wt%)/size(nm) between 0.02 and 0.1 wt%·nm^-1.
5. The literature analysis from the point of view of methodological procedures helps to highlight the lack of standard procedures to characterize nanofluids. Moreover, the results show low sampling and repeatability in the published literature.
