摘要: Abstract Despite the remarkable nanofluids potential in energy storage applications, long-term dispersion stability of nanoparticles a base fluid along with improved thermal conductivity is significant challenge towards their commercialization. Therefore, novel surfactant MWCNTs and eco-friendly Jatropha seed oil based nanofluid are synthesized via one-step synthesis method subjected to characterization visual analysis, FTIR, Zeta potential, pore size distribution, thermogravimetric analysis (TGA), UV investigate measurement. The results showed excellent improvement from 2.29% 6.76% over temperature within range 25–65 °C nanoparticle weight fraction 0.2–0.8 wt%. Furthermore, two new correlations proposed on multiple non-linear regression dimensionless group replacement classical models which failed accurate prediction conductivity. developed accuracy value R2 > 0.991.
