Enhancement of thermal transport in water and ethylene glycol using Al 2 O 3 nanoparticles Conference Paper uri icon

abstract

  • Current research demonstrates a significant increase in the thermal conductivity of suspensions containing small volume fractions (<5%) of metal or metal oxide nanoparticles compared with the base liquids alone. Due to incomplete discussion of sample preparation and characterization in a significant portion of literature to date, there is some ambiguity in what the published data actually represents. This paper provides thermal conductivity measurements for two types of nanofluids, Al 2 O 3 -deionized water and Al 2 O 3 -ethylene glycol, with a well described sample preparation method. The nanofluids were loaded at 2% by volume with 44 nm Al 2 O 3 nanoparticles. Thermal conductivity values were measured using the transient hot wire (THW) method, the nanoparticle size was obtained by small angle X-ray scattering (SAXS), and the morphology was determined by transmission electron microscopy (TEM).
