Emergent Viscous Phenomena in Ferro uids

نویسنده

  • Michael Murray
چکیده

This essay investigates the magnetoviscous properties of ferro uid ow in both an external magnetic eld and in zero eld. Zeroeld properties of ferro uids are examined. Phenomena such as the dramatic increase in ferro uid viscosity in the presensce of a static eld as well as negative viscosity for an alternating magnetic eld are described.

Lyotropic Ferronematic Liquid Crystals Based on New Ni, Cu and Zn Ionic Magnetic Fluids

The properties of lyotropic ferronematic liquid crystals based on new Ni, Cu and Zn ionic magnetic uids are discussed. The eÆciency of these new ferro uids in the lyotropic nematic liquid crystal doping is veri ed and compared with the conventional surfacted ferro uid lyotropic doping. It was observed that the structural characteristics of the lyotropics and ferro uids determine the good format...

Numerical simulation of the oscillations of non-newtonian viscous fluids with a free surface

Non-Newtonian uids are increasingly being transported by a variety of vehicles. It has been observed that vehicles containing such uids demonstrate behaviour which could be explained only by non-linearity characteristics of such uids. In this paper small oscillations of non-Newtonian uids in tanks are considered. A numerical method suitable for both Newtonian and non-Newtonian uids is suggested...

Contaminant Transfer Simulation of Unsaturated and Multiphase Flows in Porous Media

The ability to numerically simulate single phase and multiphase ow of uids in porous media is extremely important in developing an understanding of the complex phenomena governing the ow. The ow is complicated by the presence of heterogeneities in the reservoir and by phenomena such as diiusion, dispersion, and viscous ngering. These eeects must be mod-eled by terms in coupled systems of nonlin...

Issues in the statistical mechanics of steady sedimentation

A critical review is presented of recent experimental and theoretical work on the steady sedimentation of particulate suspensions in viscous ̄ uids. The point of view is that of a practitioner of non-equilibrium statistical physics rather than classical ̄ uid mechanics.
