Pore wall charge patterning and spatial profiles of electrical conductivity in short nanopores

Glavinovic M.I., Tajparast M., McGill University, CA

Artificial nanopores are now used as filters, nanofluidic switches or biosensors. Given that their functioning often critically depends on pore conductivity it is important to determine what influences the pore conductivity and how far these [...]

Spatial profiles of electrical conductivity, fluid admittance and water flow in a charged nanopore

Glavinovic M.I., Virdi G., McGill University, CA

The transport of charged particles and water through nanofluidic pores is governed by the concentration, potential and pressure gradients. Better understanding of the interplay of these forces, of the resulting fluxes of charged particles and [...]

Electrokinetic Flows in Highly Charged Micro/Nanochannel with Newtonian Boundary Slip Condition

Chun M.-S., Kim T-H., Yun J.H., Korea Institute of Science and Technology (KIST), KR

The physics of micro/nanofluids has become an area of intense interest both scientifically and technologically. The long-range nature of viscous flows and the small dimension inherent in confined spaces imply that the influence of boundaries [...]

Air Damping in an Ultra-High-Frequency Disk Resonator

Yap L.K., Yap L.Y., Ye W., Georgia Institute of Technology, US

In this paper we investigate the air damping in a circular disk radially oscillating at 1GHz. First the compressibility effects of air between the disk and the substrate are studied. The pressure perturbation along the [...]

A Stochastic Projection Method for Microchannel Flow

Ghanem R.G., Knio O.M., Le Maitre O.P., Najm H.N., John's Hopkins University, US

The construction and implementaion of a stochastic flow solver is described. The solver combines a spectral stochastic uncertainty representation scheme with a finite difference projection method for flow simulation. The uncertainty quantification scheme is based [...]
