U
ltra-high cooling performance is a crucial requirement
of many thermomechanical systems, such as
microelectronic devices, engine cooling systems, nuclear
power systems, chemical reactors, and refrigeration systems.
Recent experimental results reveal the potential thermal
properties of suspended nanometallic in conventional
fluids. In this study, the facile synthesis of one-dimensional
delafossite CuAlO
2
nanowires by microwave hydrothermal
treatment was presented. Anovel type of nanofluid consisting
of CuAlO
2
nanowires suspended in distilled water at various
volume fractions (0.0, 0.2, 0.4, and 0.6 wt.%) was successfully
synthesized using an easily scalable sonication method. The
microstructures of as-synthesized CuAlO
2
were investigated
by adopting X-ray diffraction (XRD), energy dispersive X-ray
spectroscopy (EDS), transmission electron microscopy
(TEM), and field-emission scanning electron microscopy
(FESEM). Furthermore, the thermal conductivity and specific
heat capacity of water-loaded nanofluid were measured at
different volume fractions and temperatures. The results
reveal a significant increase in thermal conductivity with
increasing CuAlO
2
loading levels and temperatures. The
obtained results propound the fact that water-loaded
delafossite CuAlO
2
nanowires-based nanofluid is a promising
candidate for future industrial applications.
