In the present work

the pool boiling critical heat flux

transient heat transfer characteristics

and bonding strength of thin Ni-Cr wire with aqua based reduced graphene oxide (rGO) nanofluids are experimentally studied. Results indicate:(i) the critical heat flux (CHF) of 0.01

0.05

0.1

0.2

and 0.3 g·L

-1

concentrations of rGO-water nanofluids varies from 1.42 to 2.40 MW·m

-2

; (ii) the CHF remains same for the tested samples during transient heat transfer studies and (iii) a constant value of CHF upto 10 tests when the nanocoated Ni-Cr wire is tested with DI water and deterioration occurs beyond this which implies a chance of peel off of rGO layer below the critical coating thickness.
