Numerical Investigation of Thermal Analysis of Coconut Oil-Based Al2O3 Nano Cutting Fluid for Sustainable Machining

Abstract

With the growing demands of sustainable manufacturing, the present research examines the development of eco-friendly fluids for machining. Sustainable machining formulated an alternative to conventional coolant by dispersing nanoparticles into an organic base oil. The investigation of this study for the heat transfer characteristic of a composite of AL2O3/Coconut oil-based nanofluid. A Maxwell mathematical model was developed with the relation of effective thermal conductivity and maximum heat dissipation from the tool/workpiece. During the analysis, we have used the nanoparticle volume fraction of (0 to 5%). The analysis findings observed that increasing the concentration by 0.05 significantly enhanced the thermal conductivity and increased the nanofluid temperature, improving heat transfer performance. In addition, the coconut oil greatly improves the dynamic viscosity of the base fluid. The study highlights the AL2O3/Coconut oil-based nanofluid as an effective and sustainable cooling medium for thermal applications in machining and other mechanical equipment.
