Abstract
CuO nanofluid was synthesized by transforming an unstable Cu(OH)2 precursor to CuO in water under an ultrasonic vibration, followed by microwave irradiation. The influences of the type of precursor, ultrasonic vibration, microwave irradiation, and dispersant were studied. The thermal conductivity of CuO nanofluid was investigated. The results show that well-dispersed CuO nanofluid with high volume fractions can be synthesized using the current method. The synthesis mechanism is proposed. The current CuO nanofluid has a higher thermal conductivity than those prepared by the dispersing method.Keywords
