The nanofluid’s thermal conductivity has been one of the most fascinating topics for researchers in this
field. So far, a large number of aqueous, non-aqueous and also oleic nanofluids are experimentally studied.
These nanofluids have been investigated with different volume fractions, various particle sizes and
different production methods. But, the question seems to be very important now is that among available
nanofluids, which one can meet our needs better? What particle sizes will work best for a chosen
nanoparticle? Whether pure experimental measuring is reliable for using a nanofluid in the industry
or not? Two nanofluids of Fe and MgO in Ethylene Glycol base-fluid with various particle sizes have been
probed in this research, and the preparation cost of these nanofluids is compared with their thermal
performance and proportionate responses are given to above questions. As well, a correlation is provided
in order to measure thermal conductivity of nanofluids in terms of thermal conductivity, particle size,
temperature and volume fraction of nanoparticles, and the data were compared with the result obtained
from a neural network modeling.
