Computational Analysis of Hydrodynamics and Light Distribution in Algal Photo-Bioreactors

V. Loomba [1], E. von Lieres [1], G. Huber [1],
[1] Forschungszentrum Jülich, Jülich, Germany

Microalgae can be directly used in health food or as biofilters for waste water treatment. They also have numerous commercial applications in cosmetics, aquaculture and chemical industry as a source of highly valuable molecules, e.g., polyunsaturated fatty acids, and they are ... En savoir plus

Modeling of Humidification using COMSOL Multiphysics®

I. Wadgaonkar [1],
[1] Tata Motors Ltd., Pune India

In the following study COMSOL Multiphysics® was used to simulate evaporation of water droplets in a stream of heated air. This was a precursor to the modeling of a humidifier, which is used to humidify the air supplied to fuel cell stack. Since the percentage of water droplets was ... En savoir plus

Multiphysics Analysis of a Thermo-Acoustic MHD Inductive Generator

R. Forcinetti [1], S. Carcangiu [1], A. Montisci [1],
[1] DIEE, University of Cagliari, Cagliari, Italy

Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus

A Numerical Euler-Lagrange Method for Bubble Tower CO2 Dissolution Modeling

D. Legendre [1], R. Zevenhoven [1],
[1] Åbo Akademi University, Turku, Finland

While the processes taking place in a bubble reactor are simple to describe in a few sentences it is much more difficult to give a physical description that is useful for engineering purposes. A better understanding of a cluster of bubbles dissolving in a liquid where the species ... En savoir plus

Micro-ARES, the Electric Field Sensor for ExoMars 2016: Atmospheric Interaction Simulations

G. Déprez [1], S. Cardnel [2], O. Witasse [2], F. Montmessin [1], F. Cipriani [2], A. J. Ball [2], F. Esposito [3]
[1] CNRS-LATMOS, Guyancourt, France
[2] ESA-ESTEC, Noordwijk, Netherlands
[3] INAF-OAC, Naples, Italy

Since 2011, LATMOS has been involved in the development of Micro-ARES, an electric field sensor forming part of the DREAMS science payload of the ExoMars 2016 Schiaparelli entry, descent and landing demonstrator module (EDM). Micro-ARES is dedicated to the very first measurement and ... En savoir plus

Investigation of Ion Interactions and Space Charge Effects in a Time of Flight Ion Trap Resonator

D. Bayat [1], I. Kjelberg [1], G. Spinola Durante [2], D. Schmid [3]
[1] CSEM SA, Neuchatel, Switzerland
[2] CSEM SA, Alpnach, Switzerland
[3] CSEM SA, Landquart, Switzerland

An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space ... En savoir plus

Modeling of Space-Charge Effects in 3D Thermionic Devices

P. Zilio [1], W. Raja [2], A. Alabastri [3], R. Proietti Zaccaria [2]
[1] Istituto Italiano di Tecnologia, Italy
[2] Istituto Italiano di Tecnologia, Italy
[3] Rice University, USA

The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due ... En savoir plus

Design of an Anisokinetic Probe for Sampling Radioactive Particles from Ducts of Nuclear Facilities

P. Geraldini [1],
[1] Sogin Spa, Rome, Italy

The aim of this study is to design a new concept of shrouded probe that meets the ISO 2889 requirements and it is suitable for small-ducts installation. In order to reduce the construction costs they have been considered standard stainless steel welding fittings manufactured according to ... En savoir plus

Elucidating the Mechanism Governing Particle Alignment and Movement by DEP

G. Zhang [1], Y. Zhao [1], J. Brcka [2], J. Faguet [2],
[1] Clemson University, Clemson, SC, USA
[2] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With ... En savoir plus

Preliminary Study of Particle Trajectory and Secondary Flow in Bend Configurations to Reduce Erosion

O. Ayala [1], A. Arruda [2], L. Calembo [2], E. Enes [2], D. Monteiro [2], R. Paizante [2], A. Rocha [2], M. Simões [2], J. Michaeli [1],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA
[2] Brazil Scientific Mobility Program, CAPES, Brasilia, DF, Brazil

To the best of our knowledge, only few researchers have made attempts to minimize the erosion in bends by modifying the bend configuration in order to alter the particle-laden flow pattern to reduce the erosion. In this work, we revisited those previously proposed bend configurations to ... En savoir plus
