ABSTRACT This study investigates the thermal properties of lauric acid (LA) as a phase change material (PCM) using K ‐Means clustering method to analyze melting characteristics. focuses on optimization PCMs hybrid methodology analytic hierarchy process (AHP) and clustering. LA, enhanced with zinc oxide (ZnO) nanoparticles, was evaluated for its performance. LA's suitability PCM is based initial temperature, heating rate, final time melt. AHP employed determine weightage three critical outcomes: latent heat, point, conductivity. The weightages assigned were 59%, 31%, 11%, respectively, reflecting relative importance each outcome in assessing efficiency LA PCM. Furthermore, then applied categorize data these weighted outcomes. utilized input parameters, assigning 27% 15% 22% underscoring their significance analysis. optimal conditions identified an temperature 24.8°C, ieating rate 5.6°C/min, 81.4°C, melt 10.6 min. These resulted outcomes 208 J/g point 80.9°C, conductivity 0.21 W/m·K. approach provides robust framework optimizing performance, facilitating energy storage release practical applications.

Biodiesel, an environmentally friendly alternative to diesel fuel, is commonly used in compression-ignition engines. In this research, attempt has been made evaluate the performance, combustion, and emission characteristics of Chlorella vulgaris algae methyl ester (CVAME) blended with fuel containing titanium oxide nanoparticles as a additive single-cylinder four-stroke engine under various operating conditions. The morphology synthesized was investigated by EDX, SEM, TEM. samples for testing were CVAME20, CVAME20 + 50 ppm TiO 2 , 100 . analyzed their physicochemical accordance ASTM procedures. From experimental results obtained, it found that offered highest reduction brake-specific consumption (BSFC). Further, blend showed 2.96% increase brake thermal efficiency (BTE) over CVAME20. However, had heat release rate (HRR) value among all at 45.41 J/° CA cylinder pressure 70.72 bar. Under peak load, exhibited reductions 35.1% CO, 31.5% HC, 9.04% smoke emissions compared Conversely, NO x increased 7.36% comparison A four-ball tester utilized investigate tribological different biodiesel blends conditions 1200 r/min, 75 °C, 40 kg duration 1 hour. addition into led 32.62% wear scar diameter (WSD) 16.51% decrease friction It can also be observed from SEM analysis nano-additives have lower rates
