Abstract

An experimental investigation is conducted to study the thermal conductivity of ferrofluid in the dynamic condition. Effect of magnetic field strength on thermal conductivity of Fe3O4/water ferrofluid flowing in a tube with constant heat flux at different Reynolds numbers (400–800) and volume fractions (1–2 Vol.%) is examined. A set of thermocouples arranged in the radial direction is used to obtain the ferrofluid temperature profile and consequently the thermal conductivity. The data show that the thermal conductivity increases with the nanofluid concentration. Moreover, in the absence of magnetic field, an enhancement in thermal conductivity is observed with increasing Reynolds number while an opposite trend is observed under magnetic field. Compared to the water thermal conductivity, the maximum thermal conductivity enhancement of 32.3% was obtained for the ferrofluid with concentration of 2 Vol.% at Reynolds number of 400 and under magnetic field of 800 G. Our insights into the thermal conductivity of the ferrofluid under dynamic condition provide a new data and can be used to promote the accuracy of heat transfer calculations.
