Abstract

Aluminum oxide nanofluids are enhanced heat transfer fluids that utilize the thermal conductivity of aluminum oxide (Al2O3) nanoparticles suspended within a base fluid. As technology advances, more efficient high heat flux solutions are required to manage the higher concentration of power in smaller designs.  In this review paper, data from multiple experiments pertaining to the thermal conductivity of Al2O3 nanofluids will be presented.  Information is compiled from peer reviewed and published scientific journals.  The experimental method will be explored; outlining the preparation of samples and measurement techniques.  Data and conclusions will be reviewed from experiments designed to test the dependency of thermal conductivity on multiple variables, such as size, concentration, and temperature. Findings spanning 20 years of experimentation will be evaluated and represented graphically. Furthermore, possible applications for alumina-nanofluid within consumer and industrial contexts will be discussed.
