Radiofrequency Inductive Coupled Plasmas Towards Low Pressure

M. Cavenago
Laboratori Nazionali di Legnaro
INFN
Legnaro, Italy

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... En savoir plus

Calibration of Ultrasonic Testing for Faults Detection in Stone Masonry

M. Usai[1], S. Carcangiu[1], G. Concu[2]
[1]Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari, Italy
[2]Department of Civil Engineering, Environmental and Architecture, University of Cagliari, Cagliari, Italy

In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and ... En savoir plus

Development of a Mathematical Model for an Anode Baking Process with COMSOL Multiphysics®

P. Nakate [1], D. Lahaye [1], C. Vuik [1], M. Talice [2],
[1] Delft University of Technology, Netherlands
[2] PM2 Engineering, Italy

The anode baking process has gained significant attention since the 1980s due to its importance in Aluminium industry. A good anode baking process strives to achieve multiple goals including reduction of NOx from emissions. NOx generation is mainly due to the high-temperature ... En savoir plus

Validation of DNS Techniques for Dynamic Combined Indoor Air and Constructions Simulations Using an Experimental Scale Model

T. van Goch, and A. van Schijndel
Eindhoven University of Technology, Eindhoven, Netherlands

This paper presents a study on the application of Direct Numerical Solving (DNS) techniques using an experimental scale model. COMSOL Multiphysics is promising in solving dynamic heat and air transport. The experiments can be extremely useful as benchmark for CFD codes. En savoir plus

Fluid Flow and Current Density Distribution in Large-area HT PEMFCs

G. C. Bandlamudi[1,2], C. Siegel[2], C. Heßke[1], and A. Heinzel[1,2]
[1]ZBT Duisburg, Duisburg, Germany
[2]University of Duisburg-Essen, Duisburg, Germany

High temperature polymer electrolyte membrane fuel cells (HT PEMFCs) are very promising technologies when used in combined cooling and heating power (CCHP) systems. They are operated at 160°C, offering the possibility of high tolerance to fuel impurities and a possibility to use the heat ... En savoir plus

Fluid-Structure Interaction Model of Active Eustachian Tube Function in Healthy Adult Patients

F. Sheer[1], and S. Ghadiali [1,2]
[1]Mechanical Engineering Department, Lehigh University, Bethlehem, PA, USA
[2]Department of Biomedical Engineering, Ohio State University, Columbus, OH, USA

The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors ... En savoir plus

Modeling Electric Fields in Slit Capillary Array Fluidic Actuators with Complex Electrode Geometries

J. Frey[1], A. Droitcour[1], D. Laser[1]
[1]Wave 80 Biosciences, San Francisco, CA, USA

With their small size, low manufacturing cost, fast transient response, and capacity to generate fluid power directly from small electrical power sources, microdevices incorporating electroosmostic flow (EOF) have wide-ranging applications, including newly developed high-performance ...

Mixing Layer Analysis in Variable Density Turbulent Flow

A.E. Alshayji[1]
[1]Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Safat, Kuwait

In this study, numerical simulations of mixing in turbulent flow, subject to a change in density, are performed. Attention is focused on the binary mixing between two streams of fluid in which a variable density step are formed due to a difference in the temperature. This binary mixing ... En savoir plus
