Keywords: electrical explosion of wire (EEW), nanofluid, optimization


This study has been focusing on controlling the size, oxidation, and agglomeration of the nanoparticle by adjusting the plasma of EEWL and the base fluid, including water, ethylene glycols, oil, polymeric solution and other common liquids. To identify the effect of the key parameters in EEWL, such as the applied electrical voltage, the capacitance, the length and diameter of the wire, and the solvent volume, the sensitivity analysis has been performed. Base on this analysis, the optimization of the EEWL process for producing Cu/ethylene glycol nanofluids has been carried out. In addition, its thermal conductivity and other properties were compared with other nanofluids prepared by the two-step method.
