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

Thermal Characterization of Low-Melting-Temperature Phase Change Materials (PCM)

L. Salvador [1], J. Hastanin [1], F. Novello [2],
[1] Centre Spatial de Liège (CSL), Angleur, Belgium
[2] CRM Group, Liège, Belgium

The successful implementation of a high-efficient latent heat storage system necessitates an appropriate experimental approach to investigate and quantify the variations of the Phase Change Material (PCM) thermal properties caused by its aging, as well as its potential demixing induced ...

Pulsed Electric Field Based Material Removal in Microelectrical Discharge Machining

T. Roy[1],, P. Ranjan[2], , R. Balasubramaniam[2]
[1]Homi Bhabha National Institute, Mumbai, India
[2]Bhabha Atomic Research Centre, Mumbai, India

Micro electrical discharge machining (MEDM), a scaled down version of EDM process, is a micro machining process used to fabricate micro holes and intricate shapes in electrically conductive materials irrespective of its hardness. In this process, an electric spark is generated in the gap ... Read More

CFD Investigation of a Photocatalytic Multi-Tube Reactor for Indoor Air Purification

J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1], S. Denys [1],
[1] Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

In industrial countries, people spend most of their time indoors. Stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality [1]. Integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow ... Read More

Increasing Dust Removal Efficiency of Electrodynamic Screens Using Frequency Optimization via COMSOL Multiphysics®

C. Morales [1], R. Eriksen [1], M. Horenstein [1], M. Mazumder [1],
[1] Boston University, Boston, MA, USA

Utility-scale photovoltaic (PV) and concentrated solar power (CSP) generation facilities are located in desert environments throughout the world to take advantage of the high availability of sunlight in these areas. Unfortunately, naturally occurring sandstorms in these deserts often ... Read More

Thermoviscous Acoustics – Piezoelectric Modeling and Simulation of Surface Acoustic Wave Devices

V. M. Dhagat [1], P. Dufilie [2],
[1] University of Connecticut, Mansfield, CT, USA
[2] Phonon Corporation, Simsbury, CT, USA

New drug discovery and development is costly; of all compounds investigated for use in humans, only a small fraction is approved for treatments around the world. The pharmaceutical industry has started switching from molecular drugs to protein-based drugs due to high specificity, ... Read More

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... Read More

Dynamic Study of Field and Current Distribution in Multifilamentary YBCO Thin Films

[1]Ecole Polytechnique de Montréal, Montréal, QC, Canada
[2]College of William and Mary, Williamsburg, VA, USA
[3]Air Force Research Laboratory

We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module ... Read More

Finite-Element Evaluation of Thermal Response Tests Performed on U-Tube Borehole Heat Exchangers

E. Zanchini, and T. Terlizzese
[1]Dipartimento di Ingegneria Energetica, Nucleare e del Controllo Ambientale, Università di Bologna, Bologna, Italy

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are ... Read More

COMSOL Multiphysics for Efficient Solution of a Transient Reaction-Diffusion System with Fast Reaction

M.K. Gobbert[1], A. Churchill[1], G. Wang[1], and T.I. Seidman[1]
[1]Department of Mathematics and Statistics, University of Maryland, Baltimore County, Baltimore, Maryland, USA

A reaction between chemical species is modeled by a particular reaction pathway, in which one reaction is very fast relative to the other one. The diffusion controlled reactions of these species together with a reaction intermediate are described by a system of three transient reaction ... Read More
