Microcapillary magnetorheometer

Magnetorheological fluids, (MR fluids) have been around since the 1940's. After their discovery many applications followed, such as the MR clutch and MR damper. In these applications the fluids are subjected to ultra high shear rates although no knowledge is available on what happens to the rheological properties under these conditions. In...

Rheology of a ferrofluid and magnetorheological fluid in a magnetic field

Through flow experiments, we determined the rheological properties of both a ferrofluid and a magnetorheological fluid. These rheological properties were affected by the presence of an external, variable, magnetic field. The rheology of the ferrofluid was almost unaffected by the magnetic field. The rheology of the MRF was strongly affected by...
