Ferrofluid flow under the influence of rotating magnetic fields
This work was centered in the understanding both the phenomenological experimental behavior and theoretical description of the flow of a ferrofluid under a rotating magnetic field. The ferrofluid flow under a uniform ...
Magnetorheological characterization of magneto-responsive fluids
The work presented in this dissertation focuses primarily on the rheological characterization of magneto-responsive fluids, consisting of suspensions of magnetic nanoparticles in non-magnetic liquid media. The rheology of ...
Ferrohydrodynamics studies through Brownian dynamics simulations of spherical nanoparticle suspensions
In this contribution, Brownian dynamics simulations of spherical, thermally blocked, magnetic nanoparticles under applied shear and magnetic fields were studied. Equilibrium and dynamical properties as well as rheological ...
Probing nanoscale viscosity in polymer melts using magnetic nanoparticles.
Oleic acid coated cobalt ferrite nanoparticles (CoFe2O4-OA), which relax through the Brownian mechanism, were dispersed in Polystyrene (PS) and Polybutadiene (PBD) of various molecular weights (MW). These suspensions were ...
