²CEMEF, MINES ParisTech, Sophia Antipolis, France
³Safran Additive Manufacturing, Paris, France

The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... En savoir plus

Model of a Filament Assisted CVD Reactor

J. Brcka[1]

[1]TEL US Holdings, Inc., Technology Development Center, Albany, New York, USA

In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... En savoir plus

Single-Phase Modeling in Microchannel with Piranha Pin Fin

X. Yu [1], C. Woodcock [1], Y. Peles [2], J. Plawsky [1],
[1] Rensselaer Polytechnic Institute, Troy, NY, USA
[2] University of Central Florida, Orlando, FL, USA

Microchannel has shown potential to dissipate high heat flux in past years [1][2]. At the same time, liquid cooling attracts more and more attention from researchers for its favorable thermal properties and ability to cool down hot and keep acceptable system temperature [3][4][5]. This ... En savoir plus

Finite Element Modeling a Redox-Enzyme-Based Electrochemical Biosensor

Y. Huang[1], and A. Mason[1]
[1]Electrical and Computer Engineering, Michigan State University, East Lansing, Michigan, USA

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak ... En savoir plus

Simulating Microbubble Flows Using COMSOL Multiphysics

X. Chen[1], and S. Ghadiali[1,2]

[1]Mechanical Engineering and Mechanics, Lehigh University, Bethlehem, PA, USA
[2]Bio Engineering program, Lehigh University, Bethlehem, PA, USA

Acute respiratory distress syndrome (ARDS) is a severe lung disease caused by a variety of direct and indirect insults. The main treatment for ARDS is mechanical ventilation. The ventilation of fluid filled lungs involves the propagation of microbubbles over a layer of epithelial cells. ... En savoir plus

Depth-Averaged Modeling of Groundwater Flow and Transport

P. Kitanidis
Civil and Environmental Engineering, Stanford University, Stanford, CA, USA

In many groundwater studies, the areal extent of an aquifer is much larger than its thickness so that flow and transport take place primarily in horizontal directions. Thus, the most common type of modeling in practical applications is two-dimensional involving vertically averaged ... En savoir plus
