Corner Charge Singularity of Conductors

Hwang C-O, Given J.A., Inha University, KR

In this paper, we investigate a diffusion-based simulation method for the corner singularity of a conducting object, rapidly evaluating the power-law singularity associated with the corner of the conducting object for the computation of capacitance [...]

InAs/GaAs Quantum Ring in Energy Dependent Quasi Particle Effective Mass Approximation

Filikhin I., Suslov V.M., Deyneka E., Vlahovic B., North Carolina Central University, US

Considered is three-dimensional In/As quantum ring using energy dependent quasi-particle-effective-mass approximation. This model was first used by Y. Li et al. (Y. Li, O. Voskoboynikov, C.P. Lee, 2002 Technical Proceedings of International Conference on Modeling [...]

A Numerical Algorithm for Complex Biological Flow in Irregular Microdevice Geometries

Trebotich D., Colella P., Miller G.H., Nonaka A., Marshall T., Gulati S., Liepmann D., Lawrence Livermore National Laboratory, US

We present a numerical algorithm to simulate non-Newtonian flow in complex microdevice components. The model consists of continuum viscoelastic incompressible flow in irregular microscale geometries. Our numerical approach is the projection method of Bell, Colella [...]

Simulation of Carbonaceous Mesophases Micro-Textures

de Andrade Lima L.R.P., Rey A.D., McGill University, CA

Carbonaceous mesophases are liquid crystalline precursor that can be spun into carbon fibers using the melt spinning process; the manufacture optimization requires a better understanding of the principles that control the carbon fiber structure development [...]

Decay of Nanostructures

Hausser F., Voigt A., Research Center Caesar, DE

The thermal relaxation of isolated (single layer) homoepitaxial islands and craters and of isolated nanomounds is simulated using a 2+1 dimensional step flow model. Numerical simulations based on adaptive finite elements are used to study [...]

New Computational Methods for Long-Range Electromagnetic Interactions on the Nanoscale

Tsukerman I., Friedman G., Halverson D., The University of Akron, US

The Flexible Local Approximation MEthod (FLAME) proposed recently by one of the authors is shown to be efficient for the simulation of long-range electromagnetic interactions between nanoparticles. Other promising applications of FLAME include charge or [...]

Modelling Micro-Rheological Effects in Micro Injection Moulding with Dissipative Particle Dynamics

Kauzlaric D., Greiner A., Korvink J.G., University of Freiburg, Germany, DE

It will be demonstrated how Dissipative Particle Dynamics (DPD), a particle based simulation method, can contribute to the rheological study of fluids in micro-cavities, e.g. in Micro Injection Moulding. It is already known that DPD [...]

Numerical and Analytical Studies of Electrothermally Induced Flow And Its Application For Mixing and Cleaning in Microfluidic Systems
