Simulation of Highly Nonlinear Electrokinetics Using a Weak Formulation

G. Soni[1], T. Squires[2], and C. Meinhart[1]

[1]Department of Mechanical Engineering, University of California Santa Barbara, CA, USA
[2] Department of Chemical Engineering, University of California Santa Barbara, CA, USA

We present a numerical model for simulating highly nonlinear electrokinetic phenomena, which occurs at high zeta potentials. In this model, the electric double layer is realized by solving a partial differential equation (PDE) on the double-layer-inducing surface. We also allow for a ... En savoir plus

Dynamic Simulation Of Particle Self-Assembly Applied To Microarray Technology

V. Di Virgilio, A. Coll, S. Bermejo, and L. Castañer
Universitat Politecnica de Catalunya, Barcelona, Spain

In this work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include ... En savoir plus

Voltage and Capacitance analysis of EWOD system using COMSOL

D. Das[1], S. Sohail[1], S. Das[2], and K. Biswas[1]

Simulation of a New PZT Energy Harvester with a Lower Resonance Frequency Using COMSOL Multiphysics®

H. Elbahr[1], T. Ali[1,2], A. Badawi[1], S. Sedky[1]
[1]Zewail City of Science and Technology - Cairo, Cairo, Egypt
[2]Cairo University, Cairo, Egypt

Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low ... En savoir plus

FEM Modeling of Electric Field and Potential Distributions of MV XLPE Cables Containing Void Defect
