Prediction of Air Permeability Using a Finite Element Method

A. Pezzin[1], A. Ferri[1]
[1]Politecnico di Torino, Torino, Italy

Air permeability is one of the most important parameters in the study of thermo-physiological comfort of fabrics. The main goal of this work is to develop a virtual process that allows the prediction of air permeability of any fabric without realizing a sample. The Free and Porous Media ... En savoir plus

Design Of Acoustic Metamaterials Based On The Concept Of Dual Transmission Line

A-S.Moreau[1], H.Lissek[1], and F. Bongard[2]
[1]Ecole Polytechnique Fédérale de Lausanne, Switzerland
[2]JAST SA, Antenna Systems, Lausanne, Switzerland

In this context, a one-dimensional acoustic transmission line, exhibiting metamaterial properties, is presented. It is composed of an acoustic waveguide, periodically loaded with membranes having the function of series capacitances, as well as transversally connected open channels ... En savoir plus

Poroelasticity Benchmarking for FEM on Analytical Solutions

E. Holzbecher[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. En savoir plus

Mathematical Model for Prediction of Transmission Loss for Clay Brick Walls

J. Ratnieks[1], A. Jakovics[1], J. Klavins[1]
[1]Laboratory for Modeling Technological and Environmental Processes, University of Latvia, Riga, Latvia

A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. En savoir plus

Advanced Topics in Acoustics Simulation

M. J. Herring Jensen [1]
[1] COMSOL A/S, Lyngby, Denmark

In this session, we will discuss and showcase a few examples of advanced acoustics applications. In this context, “advanced” means problems that cannot simply be modeled “out-of-the-box,” but require the flexibility and strengths of COMSOL Multiphysics® software. Topics include: • ...

Numerical Simulation of Electrolyte-Supported Planar Button Solid Oxide Fuel Cell

A. Aman[1], R. Gentile[1], Y. Chen[1], X. Huang[2], Y. Xu[1], N. Orlovskaya[1]
[1]Department of Mechanical, Materials and Aerospace Engineering, University of Central Florida, Orlando, FL, USA
[2]Department of Mechanical Engineering, University of South Carolina, Columbia, SC, USA

Solid oxide fuel cells (SOFCs) are electrochemical conversion devices that utilize ceramics as their electrolyte material for oxygen conduction. Compared to other types of fuel cells, they operate at relatively high temperatures, typically 400°C to 1000°C, and have an electrical ... En savoir plus

Simulation Bubble Nucleation and Bubble Growth of a Thermal-Bubble Microejector

Z. Hongwei[1] and A.M. Gué[1]
[1]Laboratoire d’Analyse et d’Architecture de Systèmes, Université de Toulouse, Toulouse, France

The present study investigates simulation model and droplet ejection performance of a thermal-bubble microejector. This model simulates the bubble nucleation and the bubble growth, to predict the droplet ejection process. Specificity, it is achieved by coupling an electric-thermal model ... En savoir plus

Actively Controlled Ionic Current Gating In Nanopores

G. Zhang[1], S. Bearden[1]
[1]Clemson University, Clemson, SC, USA

It is necessary to understand and control nanopore behavior in order to develop biosensors for a variety of applications including DNA sequencing. The fluidics of nanopore devices we fabricated exhibits a range of interesting phenomena, such as enhanced conductance and current ... En savoir plus

Multiscale Modeling of Polymer Crystallization

R. Spina[1], M. Spekowius[2], C. Hopmann[2]
[1]Dept. of Mechanics, Mathematics and Management (DMMM), Politecnico di Bari, Bari, Italy.
[2]Institute of Plastics Processing (IKV), RWTH Aachen, Aachen, Germany.

The manufacturing of high quality injection molded parts requires a deep understanding of material properties, process parameters and product design. The behavior of a polymer during the injection molding process and the performance of the final part are strongly determined by the ... En savoir plus
