Fluid Dynamics Modeling of an Industrial Wet Chemical Process Bath for the Si-Solar Cell Production

L. Mohr [1], M. Zimmer [1], A. Moldovan [1], M. Menschick [2], B. Mandlmeier [2],
[1] Fraunhofer Institut for Solar Energy Systems ISE, Freiburg, Germany
[2] Singulus Technology AG, Fürstenfeldbruck, Germany

Silicon solar cells are produced in a series of different process steps in which wet-chemical etching and rinsing steps have a considerable influence on the quality of the wafers. Etching baths are used for surface structuring or intended etch back. Examples therefore are texturing, ... En savoir plus

Multiphysics Process Simulation of the Electromagnetic-Supported Laser Beam Welding

M. Bachmann, V. Avilov, A. Gumenyuk, and M. Rethmeier
BAM Federal Institute for Materials Research and Testing
Berlin, Germany

The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... En savoir plus

Two Step Study of Flow in an Industrial Pulp Screen, Solved with the COMSOL Multiphysics® Mixer Module

R. Wetind[1]
[1]Wetind Technology AB, Alnö, Sweden

An industrial pulp screen is investigated. The dilute pulp is pumped through a screen barrier. In order to avoid the fiber network to plug, it is necessary to 1) fluidize the shear thinning pulp 2) expose the barrier with plug releasing pressure pulses. This work involves a 2-step ...

Use of COMSOL In Aerodynamic Optimization of the UNLV Solar-Powered Unmanned Aerial Vehicle

L. Dube, W. McElroy, and D. Pepper

University of Nevada, Las Vegas, Nevada, USA

We discuss the use of COMSOL Multiphysics 3.4 in the aerodynamic optimization process of the UNLV solarpowered UAV. We also address the use of COMSOL’s Multiphysics ability and how it was used within the scope of the project. In particular we highlight the development of wingtip devices, ... En savoir plus

Helium Two-Phase Flow in a Thermosiphon Open Loop

B. Baudouy[1] and F. Visentin[1]
[1]CEA, Irfu, SACM, Gif-sur-Yvette, France

The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... En savoir plus

COMSOL Modelling of a Planar Micro Ion Mobility Spectrometer

R. Cumeras, I. Gràcia, E. Figueras, L. Fonseca, J. Santander, M. Salleras, C. Calaza, N. Sabaté, and C. Cané
Instituto de Microelectrónica de Barcelona, Barcelona, Spain

A micro Planar Ion Mobility Spectrometer (P-FAIMS) has been simulated using multiphysics software. In P-FAIMS target ions are discriminated by the application of the proper separation voltages to the electrodes of the system. Modelling of vapour phase ions of two compounds have been ...

Aerodynamic Analysis of a Ski Jumper: a CFD Approach

R. Latchman [1], A. Pooransingh [1],
[1] The University of the West Indies, St. Augustine, Trinidad and Tobago

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), ...

Electrophoresis and Electroosmosis in the Intracellular Transport of Macromolecules

V. Andreev
University of Miami
Miami, FL

Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the ... En savoir plus

Study of the CO2 Transfer Rate in a Reacting Flow for the Refined Sodium ...

Study of the CO₂ Transfer Rate in a Reacting Flow for the Refined Sodium Bicarbonate Production Process

C. Wylock[1], A. Larcy[1], P. Colinet[1], T. Cartage[2], and B. Haut[1]
[1]Université Libre de Bruxelles, Brussels, Belgium
[2]Solvay S.A., Brussels, Belgium

This work deals with the quantification of the CO2 transfer rate from a bubble to the surrounding liquid in a bubble column. A model is successfully developed using COMSOL Multiphysics. The validated model is used to study the enhancement influence of chemical reactions on the transfer ... En savoir plus

Newtonian and Non-Newtonian Blood Flow over a Backward-Facing Step: Steady-State Simulation

M.W. Siebert[1], and P.S. Fodor[1]
[1]Physics Department, Cleveland State University, Cleveland, Ohio, USA

In this work, the fluid flow over a 2D backward-facing step is analyzed in order to provide a case study for the use of different models for the blood dynamic viscosity in COMSOL Multiphysics. Three non-Newtonian models, as well as the Newtonian model are used to study the shear stresses ... En savoir plus
