| Description |
Dispersions of nanodiamond (average size ∼6 nm)
within dielectric insulator mineral oil are reported for their enhanced
thermal conductivity properties and potential applications in thermal
management. Dynamic and kinematic viscositiesvery important
parameters in thermal management by nanofluidsare investigated.
The dependence of the dynamic viscosity is well-described by the
theoretical predictions of Einstein’s model. The temperature
dependence of the dynamic viscosity obeys an Arrhenius-like
behavior, where the activation energy and the pre-exponential factor
have an exponential dependence on the filler fraction of nanodiamonds.
An enhancement in thermal conductivity up to 70% is
reported for nanodiamond based thermal fluids. Additional electron microscopy, Raman spectroscopy and X-ray diffraction
analysis support the experimental data and their interpretation.
