Abstract

The manufacturing industry has thoroughly Examined the use of cutting fluids improved by nanotechnology that have higher heat conductivity to increase the efficiency of drilling operations. Due to their diverse physical & chemical characteristics and environmental compatibility, ionic liquids show significant promise for use as cutting fluids. This study examines how well different combinations of ionanofluids with nanoparticles perform as cutting fluids in drilling, by analyzing heat transfer through computational fluid dynamics and Ansys Fluent software. The thermal properties of a mixture containing TiO2, Al2O3, and Multi-walled carbon nanotube (MWCNT) nanoparticles are studied by mixing them with the ionic fluid 1-ethyl-3-methylnidazolium tetra-fluoroborate at various Reynolds numbers and particle volume fractions. Inconel 718 titanium alloy is used to make the workpiece, and tungsten carbide-cobalt is used to make the drill bit. The drilling temperature of the pure ionic liquid decreases by 23.18% with the addition of MWCNT and ionic coolant.  While the particle volume (%) remains higher. For pure ionic coolant, the Al2O3, TiO2, and MWCNT ionanofluids improve the mean heat transfer coefficient by 33.44%, 44.32%, and 59.05%, respectively. When it comes to thermal efficiency and rate of heat dissipation, MWCNT nanocoolants outperformed Al2O3 and TiO2 ion nanocoolants.
