Abstract:
This article investigates the effect of magnetic field on the viscosity of Fe۳O۴-water magnetic nanofluid experimentally. Experiments were done in the volume fraction range ۰ to ۱ vol% and the temperature ranges from۲۵ to ۴۵ ˚C. The results showed that the viscosity increased with increasing of nanoparticle volume fractions and decreased with temperature enhancement with or without of magnetic field. Also, it is observed that the viscosity of the magnetic nanofluid increases with enhancement of magnetic field strength. Thus, magnetic field is a basic factor that influences the viscosity of the magnetic nanofluids and magnetic nanofluid flow can be controlled by applying a magnetic field.
