We have investigated the structural properties of a fluid in which particles, interacting via soft potentials, are imbibed into a disordered porous structure built up by soft particles. Using a Gaussian potential for all interactions involved, we determine via Monte Carlo simulations and integral-equation theory the fluid-fluid, fluid-matrix, connected, and blocked structure factors. Within the...

It is known that emulsions can be stabilized by the presence of particles that get trapped at fluid-fluid interfaces and prevent adjacent drops from coalescing with one another. We show here that such emulsions, or Pickering emulsions, can be destabilized by applying external electric fields. This is demonstrated experimentally by studying water drops in decane and silicone oil drops in corn oi...

Using frozen hydrogen particles to observe rotating and quantized flows in liquid helium Gregory P. Bewley 2006 We present a novel technique for tracing liquid helium flows, and use this technique to make observations of fluid dynamics in both the normal fluid and the superfluid phases of liquid helium. To visualize fluid motions, we create a suspension of frozen hydrogen particles with diamete...

The increased interest in transdermal drug delivery has highlighted the importance of understanding fluid-particles dynamics in porous media. In this work, the fluid-mediated transport of drug particles in the Corneocytes of Stratum Corneum is investigated by means of the Lattice Boltzmann method, as coupled to a particle dynamics solver to track the trajectory of the drug particles. The numeri...

We report a light microscopy study of interactions between colloidal particles either chemically bound or physisorbed onto flexible giant vesicle fluid membranes. The particles induce pinched shape deformations of the membrane and are driven to negative curvature regions on nonspherical vesicles. The membrane distortions were found to induce interparticle attraction with a range approximately e...

Electric field induced particle-particle interactions and assembly are of great interest due to their useful applications in micro devices. The behavior of particles becomes more complex if multiple particles interact with each other at the same time. In this paper, we present a numerical study of two dimensional DC dielectrophoresis based particle-particle interactions and assembly for multipl...

rheological characteristics of al2o3, cuo and tio2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. constitutive relations for non-newtonian fluid were discussedbased on the power-law model. measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. results indicated that the nanofluid viscosity decreasedby increasing the concentrat...
