<div class="section abstract"><div class="htmlview paragraph">This study points to potentiality of studying Aluminum Oxide
(Al<sub>2</sub>O<sub>3</sub>) nanofluid on viscosity (μ) and thermal
conductivity (K) for automotive cooling system. The Al<sub>2</sub>O<sub>3</sub>
nanoparticles dispersed in 50:50 ethylene glycol-water with5 varying
concentrations of 0.1, 0.2, 0.3, 0.4 and 0.5 vol%. The viscosity at 25°C, 40°C,
60°C and 80°C was measured by using a Brookfield viscometer; and thermal
conductivity was measured by the transient hot wire method. The results indicate
that the viscosity increases with the concentration of nanoparticles but
decreases with the temperature. Due to comparative importance of thermal
conductivity with increasing temperatures and nanoparticle concentrations. In
nanofluid Al<sub>2</sub>O<sub>3</sub> can enhance heat transfer automotive
cooling system can be good performance and efficient as well as engine, in 0.5%
concentration, thermal conductivity at 25°C and increase 27% at 60°C, paranormal
found for development and Al<sub>2</sub>O<sub>3</sub> nanofluids apply can be
effective improvement at heat dissipation in automotive cooling system. Such a
study opens the door for further developments with the automotive industry in
the domain of advanced thermal management solutions.</div></div>
