“…As per this equation, the effective thermal conductivity of MRF85 (K MRF85 ) can be estimated using thermal conductivity of suspending . In order to estimate the thermal conductivity (K MRF85_0.25Ag ) of MRF85_0.25Ag using equation (1), it was assumed that silver nano-particles make a layer on the surface of the iron particles and particle volume percentage (υ) remains almost same (~ 0.3556). With this assumption, K MRF85_0.25Ag comes out to be 0.3259.…”

“…In the 'off' state condition, MR fluids exhibit an apparent viscosity in the order of 0.1 to 1 Pa·s at low shear rates. When an external magnetic field is applied, the originally magnetic particles become magnetized and behave like tiny magnets [1]. Magnetic interactions between these particles can be minimized if the magnetic particles line-up along the direction of the magnetic field.…”

Magnetorheological (MR) fluids, to be used as brake friction materials, must have high heat transfer rate to dissipate the heat generated during the braking action. The aim of this manuscript is to synthesize MR fluids with nano-silver and nano-copper particles to increase the heat transfer rate and characterize the demagnetizing effect of those particles on the shear stress of MR fluids. Five different MR fluids, containing a different percentage of silver and copper nano particles, were synthesized. Shear stresses of all five MR fluids were measured using magnetorheometer and the results have been plotted. A flywheel based MR brake experimental setup was developed to analyze the performance of synthesized MR fluids. "T" type thermocouples were used to measure the temperature distribution of the fabricated MR brake. The results of the temperature distribution of brakes containing five synthesized MR fluids have been presented and compared.

“…Examples of appropriate fluids include silicone oils, mineral oils, paraffin oils, silicone copolymers, white oils, hydraulic oils, transformer oils, halogenated organic liquids, diesters, polyoxyalkylenes, fluorinated silicones, glycols, water and synthetic hydrocarbon oils [7,2]. A combination of these fluids may also be used as the carrier component of the MRF.…”

“…Moreover, a hydrocarbon oilbased MR fluid has lower zero field viscosity, which is about 0.6 times less than the silicone oil-based MR fluid. On the other hand, a water-based MR fluid can minimize waste disposal problems and allows the particles to be easily recycled from the material (Ginder 1998;Phulé 2001).…”
