Finite Element Analysis of Cables Heating Due to PoE/PoE+

S. Francois[1], and P. Namy[2]
[1]Nexans Research Center, Lyon cedex, France
[2]SIMTEC, Grenoble, France

Power over Ethernet (PoE/PoE+) is a technology allowing to transmit data and power over the same data cable. The major concern for this technology is the degradation of data transmission performances due to the temperature increase in the cable. To have a better quantitative and ... Mehr lesen

Flow Simulation In A Submerged Membrane Bioreactor At Laboratory Scale

Y.M. Carreño-Martinez, J.M. Gozalvez-Zafrilla, J.A. Mendoza-Roca, and A. Santafé-Moros
Universidad Politecnica de Valencia, Spain

Submerged membrane bioreactor (SMBR) is an efficient technology for wastewater treatment that combines biological process and membrane filtration in one single stage. In the most usual configuration, submerged membrane hollow fibers are set in several planes. Air is introduced from the ... Mehr lesen

A Methodology For The Simulation Of MEMS Spiral Inductances Used As Magnetic Sensors

S. Druart, D. Flandre, and L.A. Francis
Université catholique de Louvain - ICTEAM, Louvain-la-Neuve, Belgium

In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program ... Mehr lesen

Modeling of an Optical Black Hole with True Gaussian Beam Incidence

X. Ni[1], A. Kildishev[1], E. Narimanov[1], and L. Prokopeva[2]
[1]Purdue University, West Lafayette, IN, USA
[2]Russian Academy of Sciences, Novosibirsk, Russia

We model an ideal optical black hole device in COMSOL Multiphysics as an electromagnetic scattering problem. The device is illuminated with a Gaussian beam which is focused at a fixed position in horizontal direction (x0) and different positions in vertical direction (y0). The device is ... Mehr lesen

Thermal Properties of Copper Tungsten with Copper Via Composite

[2]Torrey Hill Technology LLC, SanDiego, CA, USA

This study focuses on a low-cost composite material based on CuW with Cu via, which functions as a more efficient thermal path for heat conduction. A 50mm X 50mm X 1mm CuW(15/85) speciman consists an array of 30X30 uniformly distributed cylindrical Cu via attaching to a microprocessor ... Mehr lesen

Heat and Mass Transfer in a Gypsum Board Subjected to Fire

B. Weber
Swiss Federal Laboratories for Materials Science and Technology
Duebendorf, Switzerland

Heat and mass transfer through a gypsum board exposed to fire is simulated and compared to experimental data. The gypsum board is modeled as a porous medium with moist air in the pores. A dehydration front develops at the fire side and travels through the board, consuming energy and ... Mehr lesen

FEM Based Estimation of Biological Interaction Using a Cantilever Array Sensor

S. Logeshkumar, L. Lavanya, G. Anju, and M. Alagappan
PSG College of Technology
Tamil Nadu, India

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different ... Mehr lesen

A Wide Range MEMS Vacuum Gauge Based on Knudsen’s Forces

V. Sista, and E. Bhattarchaya
Microelectronics and MEMS Lab
Department of Electrical Engineering
Indian Institute of technology Madras
Chennai, India

A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free ... Mehr lesen
