High Frequency Electromagnetic Device Modeling with COMSOL: Simulation vs. Experiment

P. Alotto[1], F. Dughiero[1], F. Bressan[1], M. Bullo[1]
[1]Università di Padova, Dipartimento di Ingegneria Industriale, Padova, Italy

Computer simulation is mandatory for the optimization of electromagnetic devices. Here we concentrate on two classes of devices operating in the MHz and GHz range, namely microwave ovens and TEM cells for electromagnetic compatibility testing. In particular we concentrate on the issue ... Read More

Numerical Study of Hyporheic Flow across Bedforms of Different Type

C. Gualtieri [1],
[1] University of Napoli Federico II, Department of Civil, Architectural and Environmental Engineering (DICEA), Napoli, Italy

Despite the traditional separation between the studies of surface water and groundwater flows, it has been long recognized that rivers and aquifers are strongly connected and that their interaction gives rise to a continuous exchange of water and solutes. The volume within the porous ... Read More

Keynote Talk: Simulation-Based Approach to STEM Challenges

I. Milanovic [1]
[1] University of Hartford, Hartford, CT, USA

A new pedagogical approach to STEM challenges is currently implemented in the mechanical engineering program at the University of Hartford. This approach combines problem- and inquiry-based learning, simulations and apps with the COMSOL Multiphysics® software, and emphasizes the ... Read More

Iouri Balachov
Senior Scientist,
SRI International, Menlo Park, CA, USA

Iouri Balachov is a Senior Scientist at SRI International (Menlo Park, CA) where he is leading development of Direct Carbon Fuel Cell technology for clean and efficient power generation from coal, biomass, and a wide variety of carbon containing fuels. Prior to SRI he was an engineer at ... Read More

Fluid Flow Simulation of Preconcentration Membranes Using Finite Elements Tools

R. Inglés[1], J. Pallares[2], J.L. Ramirez[1], and E. Llobet[1]

[1]Dept. of Electronic, Electrical and Automatic Control Engineering, Universitat Rovira i Virgili, Tarragona, Spain
[2]Department of Mechanical Engineering School of Chemical
Engineering Universitat Rovira i Virgili, Tarragona, Spain

We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. ... Read More

Fruit Optical Properties Assessment by Means of Spatially Resolved Spectroscopy

E. Madieta[1], V. Piron[2], A. Flament[1], J.P. L’Huillier[2], and E. Mehinagic[1]
[1]PRES L’UNAM, ESA, Grappe, Angers, France
[2]ENSAM Paristech, Angers, France

Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the ... Read More

Electromagnetic Release Process for Flexible Electronics

G. Coryell[1][,][2]
[1]School for Engineering of Matter, Transport, and Energy, Arizona State University, Tempe, AZ, USA
[2]Chemistry Department, United States Naval Academy, Annapolis, MD, USA

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a ... Read More

Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

C. Wang[1], Y. Song[1]
[1]Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL ... Read More
