dc.description.abstractNanoparticles have several potential applications due to their advantageous properties which have been identified as the main driving force for nanofluids research. In this study, Jatropha oil, extracted from the seeds of the Jatropha plant was characterized by investigating the physico-chemical properties. The Jatropha oil was thereafter used as the base fluid for nanofluid formulation by enhancing with Titanium oxide (TiO2) at 0.1%, 0.15% and 0.2% volume concentrations. The formulated nanofluid was characterized by evaluating the thermal conductivity and degradation profile (thermogravimetric analysis). The findings revealed that the locally sourced Jatropha oil has 0.916 Specific gravity, 7.85 mg/100g Acid value, 189.33 mgKOH/g saponification value, 2190C flash point, -70C pour point, 5.09 pH, 113.4 g/100g of KOH iodine value and 32 mm2/s viscosity at room temperature. It was also found that the nanoparticle cutting fluid enhanced with TiO2 as a better thermal conductivity at 0.15% concentration compared to the pure base fluid and other enhanced nanofluid modified with 0.1 and 0.2% TiO2 concentration. In addition, the thermogravimetric analysis results (TGA and DTG) revealed that the pure jatropha oil degraded fastest with a broad peak and a wider degradation temperature range (226.12-449.69°C) compared with modified nanofluid with a smaller degradation temperature range (229.11-438.33). Therefore, it was concluded that the nanoparticle cutting fluid modified with TiO2 (0.15% concentration) can be adopted as cutting fluid for machining operations.
