Magnetorheology of Fiber Suspensions. I. Experimental Authors
SYNOPSIS This work reports a detailed study on the shear magnetorheology of suspensions of magnetic microfibers. The steady-state regime was investigated using a controlled-stress rheometer, for different concentrations of particles and under the presence of a broad range of applied magnetic fields (up to 512 kA m-1). The results were compared with those obtained for conventional magnetorheolog...
متن کاملTITLE OF THE ARTICLE: Magnetorheology of fiber suspensions. II. Theory AUTHORS:
SYNOPSIS This paper reports the first predictions of the yield stress of suspensions of non-Brownian magnetic fibers in the presence of uniform magnetic fields. The quasi-static regime of the shear deformation (before the flow onset) of the suspension is studied. Four different structures of the magnetic fiber suspensions are considered – column, zigzag, 3D stochastic and near-planar stochastic...
متن کاملThermodynamic Theory for Fiber Suspensions
In this paper three different approaches towards a continuum theory of fiber suspensions are discussed. The first one is the classical Thermodynamics of Irreversible Processes with internal variables. It derives constitutive equations for fiber suspensions on the basis of ONSAGERs phenomenological coefficients, which are related to the mechanical properties of the fibers. Secondly another metho...
متن کاملDerivation of turbulent energy of fiber suspensions
The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation tensors were the functions of space coordinates, distance between two points, and time.
