[3] University of Genova, Dept. of Sciences of Earth, Environment and Life, Genova, Italy

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the ... Read More

The Effect of Eccentricity in Fully Developed Annular Pipe Flow on Convection Heat Transfer and the Darcy Friction Factor

[1] Vaughn College of Aeronautics and Technology, New York, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Eccentricity in annular channels contributes to changes in fluid flow characteristics which in turn, affects the performance and integrity of the configuration. This research investigates a model of an annular channel with a diameter ratio of 0.762, an aspect ratio of 68.9:1 and heating ... Read More

Copper Electrochemical Polishing Optimisation

A. Pérez Rodríguez [1], L. Marques Antunes Ferreira [1],
[1] CERN, Geneva, Switzerland

A new electrochemical polishing facility will be built at CERN to process copper radiofrequency structures and this in the framework of the Future Circular Collider study. This polishing installation will be designed and assembled so that the necessary working conditions to achieve the ... Read More

[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... Read More

Development of a Thermal Model Using COMSOL Multiphysics® Software

A. Oukaira [1], A. Lakhssassi [1],
[1] Department of Computer Science, Université du Québec en Outaouais à Hull, Gatineau, QC, Canada

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... Read More

Keyhole Behavior During Spot Laser Welding

V. Bruyere [1], C. Touvrey [2], P. Namy [1]
[1] SIMTEC, Grenoble, France
[2] CEA DAM, Is-sur-Tille, France

The formation of porosities in spot laser welding depends on complex thermo-hydraulic phenomena. To understand and control these mechanisms, the COMSOL Multiphysics® software is used to model both the interaction and cooling stages of an isolated impact made with a Nd:YAG pulsed laser. ...
