you can use this equation for Nusselt number correlation for Fe3O4 nanofluid
Nu=0.0059·(1+7.628·φ^0.6886·Pe^0.001)·Re^0.9238·Pr^0.4
from
Xuan, Y., and Li, Q. (2003) Investigation on Convective Heat Transfer and Flow Features of Nanofluids. J. Heat Transfer, 125 (1), 151.
Thank you Eric.
I need to calculate the effect of the magnetic field on the heat transfer coefficient of ferrofluid. Do you know any correlation about it?
Dear Ali, I think these two articles will be great assistance for you. please look at them. regards
Thank you Mohammed
The second one was interesting.
Thanks Ali
Drs Mohammed and Ali, High level papers .. I commend to use them too.
Dear Sir,
Thermo physical properties you can use following models
Viscosity of nanofluids
