Enhancement of critical heat flux in nucleate boiling of nanofluids: a state-of-art review [PDF]

open access: yesNanoscale Research Letters, 2011
Nanofluids (suspensions of nanometer-sized particles in base fluids) have recently been shown to have nucleate boiling critical heat flux (CHF) far superior to that of the pure base fluid.
