Computational Fluid Dynamics Approach to Evaluate Electrostatic Precipitator Performance

M. Ahmadi [1]
[1] Faculty of Engineering Technology, University of Twente, Enschede, The Netherlands

Electrostatic precipitation is an extremely efficient way of filtering fine particles from the airstream. Electrostatic precipitators (ESPs) can control airborne emission without significantly slowing down the rate of flow, because of the low pressure drop across this type of filters. A ... Read More

Radiofrequency Ablation and Its Effect on Heat Generation on Ground Pads

J. J. Barrett [1], M. Brown [1,][2],
[1] Halyard Health, Alpharetta, GA, USA
[2] Georgia Institute of Technology, Atlanta, GA, USA

Radiofrequency ablation (RFA) is a minimally invasive procedure that can be used to treat chronic pain. Radiofrequency (RF) energy is emitted through a probe that is placed near a sensory nerve in the region of pain. The RF energy excites the nearby ions in the tissue causing them to ... Read More

Electroceutical Modeling with Advanced COMSOL® Techniques

[3] Livanova Neuromodulation, Houston, TX, USA
[4] Rush Medical Center, Chicago, IL, USA
[5] University of New South Wales, Sydney, NSW, Australia

Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... Read More

Gas Permeation Through the Polymeric Membrane – Fluid Behavior in the Permeate Channel

M. Szwast[1]
[1] Department of Chemical and Process Engineering, Warsaw University of Technology, Warsaw, Poland

For membrane gas separation modeling, some assumptions are made. One of the most typical approaches in such modeling is to assume a plug flow in the feed/retentate channel and ideal mixing conditions in the permeate channel. For membranes with high permeation, the permeate flux could be ... Read More

A Fluid Particle Simulation to Study the Motion Sickness in Semicircular Canal

C. Park[1], J. Lee[1]
[1]Altsoft Inc., Seoul, South Korea

The vestibular systems are very important to balance of body. But some people have vertigo and dizziness caused by vestibular disorder. It is well known how the symptom appears physiologically. The benign paroxysmal positional vertigo (BPPV) which comes from moving an otolith in ... Read More

Effects of Geometry and Operating Conditions on Membrane Reactor for Water Gas Shift Reaction

D. Shin [1], T. Kim [1], J. Lee [1]
[1] Altsoft Inc., Seoul, South Korea

Recently, hydrogen is widely used as environmental energy and high energy content. The hydrogen is mainly produced by water gas shift reaction(WGSR) from coal to hydrogen process in Integrated Gasification Combined Cycle(IGCC) plant. WGSR, well known for hydrogen production, is a ... Read More

Urban Air Purification Using Semi-Active Photocatalysis

M. Boumahdi [1], J. Roegiers [2] , C. El Amrani [1] , S. Denys [2]
[1]Department of Computer Engineering, Abdelmalek Essaadi University, Tangier, Morocco
[2]Sustainable Energy, Air & Water Technology, Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Photocatalysis has received considerable attention in recent years with a huge potential in air purification applications. This work focusses on the semi-passive use of photocatalytic surfaces in streets as an innovative method for removing anthropogenic pollutants (especially volatile ... Read More

COMSOL® Simulation of Blister Actuated Laser Induced Forward Transfer (Ba-LIFT)

M. Morales [1], , J. J. Moreno [1] , D. Munoz-Martin [1] , C. Molpeceres [1]
[1]Centro Láser UPM, Universidad Politécnica de Madrid, Madrid, Spain

Laser-induced forward transfer (LIFT) is a non-contact direct-write technique that enables the deposition of small volumes of material into user-defined high-resolution patterns with a wide range of structural and functional materials. There are many variations of the LIFT process, each ... Read More

Modeling of Electro-Thermal Microbolometer for Thermal Imaging

A. Nowicki [1], A. Bennecer [1],
[1] Mechanical Engineering, University of Northampton & Gdańsk University of Technology, Gdańsk, Poland
[2] Engineering, University of Northampton, Northampton, United Kingdom

A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... Read More

Simulation and Design of Lithium Ion Battery Packs for the Altitude Conditions in Northern Chile

A. Mallco Carpio [1], M. Cortes Carmona [1],
[1] University of Antofagasta, Antofagasta Energy Center, Antofagasta, Chile

One of the most noticeable effects in loss of performance and capacity of thermal systems is produced by altitude. This causes that the density of a compressible fluid and the atmospheric pressure are considerably reduced, causing a decrease in electrical power and thermal systems. Given ... Read More
