Modeling permeation through anisotropic zeolite membranes with nanoscopic defects

We have modeled permeation through anisotropic zeolite membranes with nanoscopic defects that create shortcuts perpendicular to the transmembrane direction (x). We have found that the dimensionless ratio Dy /(kd1y) can be used to estimate whether the shortcuts contribute significantly to the overall flux. Here Dy is the diffusion coefficient for motion in the plane of the membrane, kd is the ra...

Elasticity of synovial fluid.

Anisotropic elasticity of experimental colloidal Wigner crystals.

Colloidal particles interacting via a long-range repulsion can, in contrast to hard-sphere systems, exhibit crystalline ordering at low volume fraction. Here we experimentally investigate the structure and properties of such "colloidal Wigner crystals." We find a body-centered-cubic crystalline phase at volume fractions of ϕ≳15%, which exhibits large fluctuations of individual particles from th...

Modeling Fluid Flow in Heterogeneous and Anisotropic Porous Media

Permeability distribution in reservoirs is very important for the flow ofwater or oil and gas. In this study, the effects of various heterogeneous permeability distributions on the flow field are simulated using the finite difference technique. We have simulated the flow for two types of heterogeneous distributions, one is Gaussian and the other is self-similar or fractal, the latter being much...
