Wireless Power and Communications for Implantable Biosensors

C. Romero[1], M. Mujeeb-U-Rahman[1]
[1]California Institute of Technology, Pasadena, CA, USA

Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... Mehr lesen

Low Reynolds Number Flow Around a Flying Saucer Micro Air Vehicle

S. Cortés[1], D. Güemes[1], R. Ávila[1]
[1]Universidad Nacional Autónoma de México, Mexico City, Mexico

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... Mehr lesen

Impact of a 3D EM Model Configuration on the Direct Optimization of Microstrip Structures

[1]The Jesuit University of Guadalajara. Dept. of Electronics, Systems and Informatics, Jalisco, México
[2]Intel Guadalajara Design Center, Jalisco, México

The EM optimization of a coarsely discretized model of a microstrip band-pass filter implemented in COMSOL Multiphysics® was realized using two different model configurations. We presented a systematic methodology to find an appropriate 3D EM model configuration on a direct EM ... Mehr lesen

Models with Helical Symmetry Studied in a 2D Plane

M. Weterings[1], M. Beyrer[1]
[1]Institute of Life Sciences HesSo Valais, Sion, Valais, Switzerland

Partial differential equations (PDEs) in multiple dimensions may often be solved in a lower dimension if the problem domain contains a symmetry (cylindrical, spherical, translational, etcetera). For problems involving PDEs with helical symmetry we propose a method, with both low ... Mehr lesen

Numerical Simulation of the Effect of Inlet Design on Thermal Storage Tank Performance Using COMSOL Multiphysics®

W. Yaïci[1], M. Ghorab[1], E. Entchev[1]
[1]Natural Resources Canada, CanmetENERGY, Ottawa, ON, Canada

This study presented the results of 3D unsteady CFD simulations to investigate the influence of adding a flat baffle plate at the entrance during the discharging operation on the flow behaviour, thermal stratification, and performance of a hot water storage tank installed in solar ... Mehr lesen

Water Quality Model for Brewster Lake

Z. Aljobeh[1], G. Argueta[1]
[1]Valparaiso University, Valparaiso, IN, USA

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the ... Mehr lesen

Simulation of Ground Heat Exchanger for Cryogenic Applications

F. Bergeron[1], P. Pasquier[1]
[1]École Polytechnique de Montréal, Montréal, QC, Canada

Ground freezing techniques using liquid nitrogen are commonly used in order to increase the mechanical properties of the soils. This article presents a new ground heat exchanger using aluminum to increase the effective radius of the heat exchanger. Simulation results indicate that the ... Mehr lesen

Study of the Thermal Behavior of Solar Cells Based on GaAs

N. Martaj[1,2], E. Guidicelli[2], Y. Cuminal[2], A. Perona[3], S. Pincemin[1,2]
[1]EPF-Ecole d’Ingénieurs, Montpellier, France
[2]IES, UMR5214, Université Montpellier II, Montpellier, France
[3]Laboratoire PROMES-CNRS Tecnosud, Rambla de la thermodynamique, Perpignan, France

The paper studies the thermal modeling and simulation of photovoltaic cells suitable for use in highly concentrated solar flux (> 1000 suns). The cells studied are those of GaAs kind. These cells are a very good alternative to be studied instead of more complex multi junctions cells. ... Mehr lesen

Statistical Sensitivity Analysis of Li-ion Pouch Battery Cell Dimension and Design

A. Samba[1], N. Omar[2], H. Gualous[3], Y. Firouz[2], O. Capron[2], M. Abdel MonemO[2], J. Smekens[2], P. Van den Bossche[2], J. Van Mierlo[2]

[2]VUB ETEC, Brussel, Belgium
[3]UCBN, LUSAC, Cherbourg, France

Multi-Scale and Multi-Dimensional (MSMD) modeling approaches have been proposed to simulate the thermal, electrical distributions and concentration behaviors of large size pouch cell. This approach is based on coupling of the energy balance with the Newman’s electrode model. Newman’s 1D ... Mehr lesen

Optimization of a Rotor Shape for Spherical Actuator with Magnetically Levitating Rotor to Match Octupole Field Distribution

M. Sidz[1], R. Wawrzaszek[1], L. Rossini[2], A. Boletis[3], S. Mingard[3], K. Seweryn[1], E. Onillon[2], M. Strumik[1]
