The Role of 1D & 2D Asymmetric Diffusion Layers In Rectification Through Ion-Selective Membranes

W. Booth, J. Schiffbauer, and B. Edwards
West Virginia University
Star City, WV

Ion-selective membranes can be used in lab-on-a-chip devices for various portable applications in this field. These devices can be used as concentrators for analytical chemistry and for micro-scale filtration. Here, a binary aqueous electrolyte solution in a microchannel has a potential ... En savoir plus

Some Clinical and Computational Studies On Haemodynamics In Stenosed Artery

A. Chanda, A.R. Choudhury, G. Ray, K. Dasgupta, and D. Nag
Jadavpur University, Kolkata, West Bengal, India

Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always ... En savoir plus

A Computational Study of Stoichiometry Sensitivity of a PEM Fuel Cell with Multi-Parallel Flow Channels

M. A. Rahman [1], J. M. Mora [2], P. A. Chuang [1],
[1] School of Engineering, University of California, Merced, CA, USA
[2] University of the Philippines - Diliman, Quezon City, Philippines

Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... En savoir plus

The effect of viscosity on dynamics of Electrowetting droplet

NingWeng [1], Qinggong Wang* [1], Wei Yao* [1],
[1] Qian Xuesen Laboratory of Space Technology, China Academy of Space Technology, Beijing, China

Electrowetting (EW) has found a wide range of the potential applications including fast response displays, lab-on-a-chip microfluidic devices, and light vales. However, fundamental understanding of dynamics of EW-actuated droplet is not clear. In this work, a combined numerical approach ... En savoir plus

Investigating Magnetic and Electric Fields Couplings for 3D Models in Harmonic and Transient States

O. Maloberti [1], O. Mansour [1]
[1] ESIEE Amiens, Amiens, France

At present, no 3D transient magnetic and electric fields formulation with strong eddy currents and high electric fields is available in the physical applications with COMSOL Multiphysics® software. However, some industrial products need such a tool, as it is the case for induction coils ... En savoir plus
