Thermohydraulic Study of a Fixed Bed for the Core of a Nuclear Reactor

J. C. Almachi [1], J. A. Montenegro [1],
[1] Departamento de Formación Básica, Escuela Politécnica Nacional, Quito, Pichincha, Ecuador

The fixed beds have the advantage of large heat transfer area, for they are used in some designs of innovative nuclear reactors as the reactor FBNR. Inside of study of fixed beds is important to define the following parameters: flow minimum and velocity profile of cooling fluid, ... Read More

Thermal Modeling in a Historical Building - Improving Thermal Comfort Through the Siting of a Passive Mass of Phase Change Material

D. Groulx[1], F. Herbinger[1], L. Desgrosseilliers[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

A model of an office room was created in the COMSOL Multiphysics® software to simulate heat transfer and study the impact of siting a mass of phase change material (PCM) in a room to increase thermal comfort. This study determined that incorporating the selected PCM, butyl stearate, in ... Read More

Simulation of Horn Driver Response by Direct Combination of CD Frequency Response and Horn FEA

D. Cinanni [1],
[1] Ciare S.r.l., Italy

Today a horn driver developing is still time and cost consuming. In addition compression driver behavior depends by the horn profile. In this study is proposed a new technique to model a combination of an existing compression driver and a virtual horn, in order to predict the horn driver ... Read More

Zinc Corrosion in a Crevice

C. Taxén, and D. Persson
Swerea-Kimab, Stockholm, Sweden

Corrosion of metals in confined zones is a big industrial problem. The electrochemistry of such localized corrosion processes is complicated by the impact of the corrosion processes on the composition of the local solution. In the present problem, local interaction with the atmosphere ... Read More

Simulation of Electro-Thermal Transients in Superconducting Accelerator Magnets

L. Bortot [1], M. Maciejewski [2], M. Prioli [1], B. Auchmann [3],
[1] CERN, Geneva, Switzerland
[2] CERN, Geneva, Switzerland; Lodz University of Technology, Lodz, Poland
[3] CERN, Geneva, Switzerland; Paul Scherrer Institute, Zurich, Switzerland

The paper presents the application of COMSOL Multiphysics® software to the modelling of superconducting accelerator magnets. A 2D magneto-thermal model is developed, using an equivalent magnetization formulation to take into account the eddy-currents’ effects. Due to the model ... Read More

3D-Printed Microfluidic Chip System for Dielectrophoretic Manipulation of Colloids

I. Kuehne [1], N. Philippin [1], M. Michatz [2], A. Frey [2],
[1] Heilbronn University of Applied Science, Kuenzelsau, Germany
[2] University of Applied Science, Augsburg, Germany

INTRODUCTION: Microfluidics, as a crucial technology of recent years, enables numerous applications for Point-of-Care-Testing such as Lab-on-Chip-Systems (LOC) or Micro-Total-Analysis-Systems (µTAS) and is exceptionally well-suited for cell sorting or DNA trapping. Especially the ... Read More

Foundational Undergraduate Teaching and Research Tools In Thermoelectrics Using COMSOL Multiphysics®

D. Buna [1], L. Hoxha [1], D. Tafone [1]
[1] School of Theoretical and Applied Science, Engineering Physics, Ramapo College of New Jersey, Mahwah, NJ, USA

COMSOL Multiphysics® can play a crucial role in jumpstarting undergraduate research programs in physics and engineering at colleges with limited financial support and small faculty size. The engineering physics program at Ramapo College of NJ has 48 majors and 4 full time faculty with ... Read More

Structural and Environmental Design of a Rainscreen System Using COMSOL Multiphysics

C. Guido Galante [1], M. Donà [2],
[1] Newtecnic Ltd, London, England, UK
[2] University of Cambridge, UK

The subject of the study is a bespoke rainscreen system designed for the Grand Theatre of Rabat, Morocco (Figure 1). The project presents a complex façade geometry and consists of a 1800-seat theater, an open-air amphitheater with a capacity of 7000 people, a rehearsal space and a ... Read More

Reducing Solar Heat Gain from Inclined Buildings’ Roof by Using Radiant Barrier System

S. Ebrahim[1], A. Alshayji[1]
[1]Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait City, Kuwait

The study produced a simulated model of natural convection in an inclined rectangular channel open ended with different locations of radiant barrier (RB) along the channel thickness(S). The upper plate is heated by various uniform constant heat fluxes while the inner surface of the lower ... Read More

Efficiently Solving the Stochastic Reaction-Diffusion Master Equation in C++ with the COMSOL Multiphysics® Software

L. A. Widmer [1], J. Stelling [1],
[1] Department of Biosystems Science and Engineering, ETH Zürich and Swiss Institute of Bioinformatics, Basel, Switzerland

We demonstrate a simulation engine using COMSOL® and MATLAB® software that is able to simulate stochastic reaction-diffusion models in the reaction-diffusion master equation framework. We use this engine to construct models of budding yeast cells with embedded microtubules, interfacing ... Read More
