The effective viscosity and thermal conductivity of the nanofluid as a function of vol % of magnetite nanoparticles. The best fit on and viscosity curves are shown by the solid (red) and dashed lines, respectively. The fit with Einstein equation is shown by the dotted line.
(a) The effective and (b) viscosity enhancement as a function of magnetic field parallel to the temperature gradient at different volume fractions (0.0011, 0.004, 0.0057, 0.0082, and 0.0171) of magnetite nanoparticles.
The effective viscosity and thermal conductivity of nanofluids as a function of applied magnetic field parallel to the temperature gradient at 0.078 vol % of magnetite nanoparticles. The values indicate that fluid can act as an efficient heat transfer fluid in the regime a, as efficient coolant and damper in regime b, and as an efficient damper with moderate cooling property in regime c. The schematic in Fig. 3 shows the cooling action without and with magnetic field on. When the field is ON, the parallel mode conduction leads to extremely large enhancement in .
