Lubrication subjected to effects of electric and magnetic fields: recent research progress and a generalized MEMT-field Reynolds equation

Frontiers in Mechanical Engineering
Electric and magnetic fields have been used in various ways to enhance the performance of lubrication systems. The presence of these fields can significantly change the properties of lubricants. The rapid adoption of electric vehicles (EVs) has presented

Electrorheology of Diamond/PDMS Nanofluids in Steady and Oscillatory Shear

Applied Rheology, 2014
The rheological properties of diamond (< 10 nm) in silicone oil (PDMS) were analyzed using steady shear and oscillatory shear measurements. Unlike micron sized diamond suspensions these suspensions were non Newtonian and showed strong viscoelastic ...

A multiplicity result for a nonlinear degenerate problem arising in the theory of electrorheological fluids

, 2006
We study a Dirichlet boundary value problem associated to an anisotropic differential operator on a smooth bounded of $\Bbb R^N$. Our main result establishes the existence of at least two different non-negative solutions, provided a certain parameter ...

Electrorheology of nanofiber suspensions

Nanoscale Research Letters, 2011
Electrorheological (ER) fluid, which can be transformed rapidly from a fluid-like state to a solid-like state under an external electric field, is considered to be one of the most important smart fluids.

Electrorheological Generalized Dispersion of Soluble Matter through a Poorly Conducting Fluid Saturated Porous Media [PDF]

, 2015
In this paper, we investigate the effects of electric field, viscosity variation parameter and porous parameter on the generalized dispersion of an unsteady convective diffusion through a poorly conducting fluid in a channel bounded by rigid parallel ...

Relaxation of surface charge on rotating dielectric spheres: Implications on dynamic electrorheological effects

, 2001
We have examined the effect of an oscillatory rotation of a polarized dielectric particle. The rotational motion leads to a re-distribution of the polarization charge on the surface of the particle.

Existence for the steady problem of a mixture of two power-law fluids [PDF]

, 2012
The steady problem resulting from a mixture of two distinct fluids of power-law type is analyzed in this work. Mathematically, the problem results from the superposition of two power laws, one for a constant power-law index with other for a variable one.

On the existence of classical solution to the steady flows of generalized Newtonian fluid with concentration dependent power-law index

, 2018
Steady flows of an incompressible homogeneous chemically reacting fluid are described by a coupled system, consisting of the generalized Navier--Stokes equations and convection - diffusion equation with diffusivity dependent on the concentration and the ...
