Solving a Two-Scale Model for Vacuum Drying by Using COMSOL Multiphysics

S. Sandoval Torres[1]
[1]Instituto Politécnico Nacional, CIIDIR, Oaxaca, Mexico

Drying of porous materials is characterized by the invasion of a gaseous phase replacing the evaporating liquid phase. Vacuum drying is an advanced method applied to oakwood to diminish discoloration, so understand its physics is a very important task. In this work, a two-scale model is ... Mehr lesen

Particle Tracing: Analysis of Airborne Infection Risks in Operating Theatres

P. Apell[1], S. Hjalmarsson[1], T. Lindberg[1], I. Wernström[1], Y. Tarakonov[1], A. Erichsen Andersson[2], M. Karlsteen[1]
[1]Department of Applied Physics, Chalmers University of Technology, Göteborg, Sweden
[2]Sahlgrenska University Hospital, Department of Anesthesia, Surgery and Intensive Care, Göteborg, Sweden

Patients undergoing surgery are sensitive to infections. The operation staff may spread 10^4 particles per person per minute, of which ten percent are presumed bacteria-carrying. We visualize the influence of the personnel on the air and particle flows for the two most common ventilation ... Mehr lesen

Electric Field Density Distribution for Cochlear Implant Electrodes

N.S. Lawand[1], J. van Driel[2], P.J. French[2]
[1]Electronic Instrumentation Laboratory (EILab), Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS), Delft University of Technology, Delft, The Netherlands
[2]Delft University of Technology, Delft, The Netherlands

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large ... Mehr lesen

Simplified Numerical Model of an Axial Impeller

A.-M. Georgescu[1], S.-C. Georgescu[2]
[1]Hydraulics and Environmental Protection Department, Technical University of Civil Engineering, Bucharest, Romania
[2]Hydraulics Department, University “Politehnica”, Bucharest, Romania

We propose a simplified numerical method to model the flow field downstream of an axial impeller. The method can be used for any axial hydraulic machinery for which, one is less interested by the flow between the blades, than by the flow field downstream of the machinery. The method is ...

Fracture-Matrix Flow Partitioning and Cross Flow: Numerical Modeling of Laboratory Fractured Core Flood

R. Sanaee[1], G.F. Oluyemi[1], M. Hossain[1], B.M. Oyeneyin[1]
[1]Robert Gordon University, Aberdeen, United Kingdom

The contrast between hydro-mechanical behavior of the rock matrix and fracture network systems results in flow partitioning between fracture and matrix systems which is affected by the In-situ stress regime. Fracture flow, Darcy law and free and porous media flow physics interfaces of ... Mehr lesen

Application of COMSOL Multiphysics in the Study of Heat Transfer in Solids: Comparison with Measurements Obtained by Means of Infrared Photothermal Radiometry

V.M. Suárez Quezada[1], J.H. Wong[1], J.A. Calderón Arenas[1], E. Marín Moares[1], José Bruno Rojas Trigos[1], Antonio Gustavo Juarez Gracia[1], Jonathan F Guarachi solano[1]
[1]Centro de Investigación en Ciencia Aplicada y Tecnología Avanzada Unidad Legaria del Instituto Politécnico Nacional, Mexico, Distrito Federal, Mexico

We report the use of Heat transfer Module of COMSOL Multiphysics and a technique based on Infrared Photothermal Radiometry to study the heat transfer of a homogeneous and isotropic solid material excited by a periodic laser beam on the front side of the sample, and one infrared detector ...

Coupled Heat and Moisture Transfer in Building Components - Implementing WUFI® Approaches in COMSOL Multiphysics

B. Nusser[1], M. Teibinger[1]
[1]Holzforschung Austria, Vienna, Austria

Calculating time-dependent heat and moisture transports trough building components are important tasks in the area of building physics. A well known and worldwide used commercial software for this is WUFI®. From the scientific point of view the restricted access to governing equations is ... Mehr lesen

Modeling Thermal Bridging at Interface Conditions: Analysis of Solutions for Reducing Thermal Bridges Effects on Building Energy Consumption

C. Balocco[1], E. Marmonti[1]
[1]Dipartimento di Energetica, Università di Firenze, Firenze, Italy

In Europe considerable building activity can be expected over the coming decades; Net Zero Energy Buildings refers to a building with minimal power, until maximum 15 kW/m^2. In both cases this requires very well insulated buildings with minimal thermal bridges. Concrete balconies, that ... Mehr lesen

Web Based Laboratories for Teaching Electromagnetics for TEMPUS eLab Project

Y. El-Qattan [1], H. Ghali[1]
[1]Electrical Engineering Department, The British University in Egypt (BUE), El Sherouk City, Egypt

This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, ... Mehr lesen

Numerical Aspects of the Implementation of Artificial Boundary Conditions for Laminar Fluid-Structure Interactions

C. Boeckle[1], P. Wittwer[1]
[1]University of Geneva, Geneva, Switzerland

We discuss the implementation of artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a finite domain for numerical purposes, artificial boundaries appear. We present an ... Mehr lesen
