Dynamics and electrorheology of sheared immiscible fluid mixtures

Dynamics and electrorheology of sheared immiscible fluid mixtures.

We analyze the electrorheological effect in immiscible fluid mixtures with dielectric mismatch. By taking the electric field effect into account, which couples to the dynamics of domain morphology under flow, we propose a set of electrorheological constitutive equations valid under the condition where the relative magnitude of the flow field is stronger than that of the electric field. Through ...

Nonequilibrium dynamics and fluctuation-dissipation relation in a sheared fluid

The nonequilibrium dynamics of a binary Lennard-Jones mixture in a simple shear flow is investigated by means of molecular dynamics simulations. The range of temperature T investigated covers both the liquid, supercooled, and glassy states, while the shear rate g covers both the linear and nonlinear regimes of rheology. The results can be interpreted in the context of a nonequilibrium, schemati...

Dynamics of fluid mixtures in nanospaces.

A multicomponent extension of our recent theory of simple fluids [U. M. B. Marconi and S. Melchionna, J. Chem. Phys. 131, 014105 (2009)] is proposed to describe miscible and immiscible liquid mixtures under inhomogeneous, nonsteady conditions typical of confined fluid flows. We first derive from a microscopic level the evolution equations of the phase space distribution function of each compone...

Fluid-Fluid Collision for Particle-Based Immiscible Fluid Animation

In this paper, we propose a new fluid-fluid collision model for particle-based immiscible fluid animation. Our model consists of two components, namely, collision detection and collision response. An interesting feature is that our model not only can prevent immiscible fluids from mixing with each other, but also can allow one fluid to run through or to wrap around another fluid. The model is v...
