Multiphysics Simulation of Space Charge and Electric Field for Liquid Argon Neutrino Detector

S. D. Luise [1], L. M. Bueno [1],
[1] ETH Zurich, Zurich, Switzerland

The DUNE experiment (http://www.dunescience.org/) is an international collaboration of more than 100 research institutes and universities (among them CERN and Fermilab) which is taking the challenge of building the next-generation experiment for the study of neutrino particles. The ... Read More

Model of Pressure Drop Separation during Aqueous Polymer Flow in Porous Media

D. C. Raharja [1], R. E. Hincapie [1], M. Be [1], C. L. Gaol [1], L. Ganzer [1],
[1] Clausthal University of Technology, Clausthal-Zellerfeld, Germany

Aqueous polymers used for enhanced oil recovery (EOR) application is considered a complex fluid. It can exhibit Newtonian and Non-Newtonian behavior depending on the velocity or the stresses that it is submitted during the flooding process. Therefore, the polymer flooding project ... Read More

Use of COMSOL Multiphysics® Software for Physics Laboratory Exercises

H. van Halewijn [1],
[1] Fontys Hogeschool, Applied Physics, Eindhoven, Netherlands

COMSOL Multiphysics® is used to simulate thermal flow experiments at out University for Applied Physics. Students have to measure thermal flow problems and verify the measurements with detailed simulations. The desired accuracy is 5% or less. The presentation will cover 3 laboratory ... Read More

Modeling and Simulation of Flat Sheet Membrane with Physical and Chemical Absorption

N. Ghasem [1], M. Al-Marzouqi [2],
[1] UAE University, Al-Ain, UAE
[2] UAE University, Al-Ain, UAE

Greenhouse gases trap heat and make the planet warmer. The main greenhouse gases emitted by human activities are: Carbon dioxide (CO2). The use of fossil fuel is the primary source of CO2 [1, 2]. Accordingly, there is a need for an efficient and novel separation processes for removal of ... Read More

Aluminization Process from Ionic Liquid in Operative Conditions: Validation and Perspective

A. Giaccherini [1], E. Berretti [2], S. Martinuzzi [1], S. Caporali [1],
[1] INSTM, Firenze, Italy
[2] Department of Chemistry, University of Florence, Firenze, Italy

This work is a first evaluation of the validity of the frozen rotor approximation for the simulation of a stirred beaker. The agreement is good, further analysis will be carried before using the model to optimize labscale setup dedicated to IL electrochemistry. Read More

Optimization of Drying Step to Obtain Large, Transparent Magnesium-Aluminate Spinel Ceramics

J. Petit [1], L. Lallemant [1],
[1] ONERA, Chatillon, France

To obtain large transparent ceramic samples, we optimized the drying step process using COMSOL Multiphysics®. Indeed, green body's drying in a climate chamber is the critical step when large size and complex shape samples are needed. Then we obtained 75 mm diameter and 10 mm thickness ... Read More

Migration of Mineral Oil Saturated and Aromatic Hydrocarbons(MOSH, MOAH) through Multi-Layered Packaging into Food

C. Kirse [1], F. Edel [1], H. Briesen [1],
[1] Chair of Process Systems Engineering, Technical University of Munich, Germany

Substances like Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) are suspected to be carcinogenic. Furthermore, MOSH/MOAH migrate through the packaging into food stuff. This work aims at modelling, how much MOSH/MOAH migrates from the packaging into ... Read More

Modeling Migration-Diffusion-Reaction Processes in an Idealized Lithium-Sulfur Cell

G. Minton [1], R. Purkayastha [1], S. Walus [1], M. Marinescu [2], T. Zhang [2], G. Offer [2],
[1] Oxis Energy Ltd, Oxford, United Kingdom
[2] Imperial College London, London, United Kingdom

During the basic operation of a lithium-sulfur (Li-S) cell, sulfur molecules are required to undergo a complex mix of electrochemical and chemical reaction processes. To date, almost all modeling of Li-S cell behavior has been undertaken using electroneutral, structurally homogenized, ... Read More

Implementation of a Porous Media Model for Simulating Pressure Development in Heated Concrete

B. Weber [1], D. Dauti [2], S. Dal Pont [2],
[1] Empa, Swiss Federal Laboratories for Materials Science and Technology, Dübendorf, Switzerland
[2] Laboratoire 3SR, University Grenoble Alpes, Grenoble, France

When concrete is subjected to high temperature, capillary water evaporates and chemically bound water is released due to dehydration. This results in an increase of pore pressure, which is believed to be one of the mechanisms leading to spalling. Spalling of concrete is of high concern ... Read More

Hygrothermal Modeling: A Numerical and Experimental Study on Drying

M. Bianchi Janetti [1], F. Ochs [1], L. P. M. Colombo [2]
[1] University of Innsbruck, Unit for Energy Efficient Buildings, Innsbruck, Austria
[2] Dipartimento di Energia, Politecnico di Milano, via Lambruschini 4, 20156 Milan, Italy

A model for coupled heat and mass transfer in porous, capillary-active materials is validated against experimental data obtained by drying calcium silicate specimens. The accuracy of the numerical solution is qualitatively investigated by considering mass conservation for a set of ... Read More
