Numerical Results of Two 3D Coupled Models of a Unitary PEM Fuel Cell of 144cm²

E. Robalinho[1], E. F. Cunha[2], M. Linardi[2]
[1]Universidade Nove de Julho - UNINOVE, São Paulo, SP, Brazil
[2]IPEN/CNEN-SP, São Paulo, SP, Brazil

This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and ... 詳細を見る

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... 詳細を見る

Models of Simple Iron Cored Electromagnets

J. Mammadov[1]
[1]University of Manchester, Manchester, UK

This report mainly discusses the implementation and results of a project proposal, “Modelling using Finite Element Methods”. The report is devoted to implementation, which is a model of an electromagnet. The software tool that is used to model the electromagnet is COMSOL Multiphysics®, a ... 詳細を見る

Modal Analysis of Functionally-Graded Metal-Ceramic Composite Plates

E. Gutierrez-Miravete[1], W. L. Saunders II[2], K. Pendley[3]
[1]Rensselaer at Hartford, Hartford, CT, USA
[2]General Dynamics Electric Boat, Groton, CT, USA
[3]United Technologies - Pratt & Whitney, East Hartford, CT, USA

The determination of the modes of vibration of Functionally Graded-Metal-Ceramic Composite plates is important in practice in order to prevent undesired resonances in structural components. This paper describes the application of COMSOL Multiphysics® software for the determination of the ... 詳細を見る

Analysis of Mash Tun Flow: Recommendations for Home Brewers

E. Gutierrez-Miravete[1], C. J. Walsh[2]
[1]Rensselaer at Hartford, Hartford, CT, USA
[2]General Dynamics-Electric Boat, Groton, CT, USA

The major steps in the beer making process are simple and with some skill, rather good brew can be produced using a common picnic cooler. First, grain (usually barley) is wetted and allowed to partially germinate before dried in a kiln (malting) Next, during mashing in a mash tun ... 詳細を見る

Energy Pile Simulation – an Application of THM-Modeling

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

Energy piles, i.e. heat exchangers located within the foundation piles of buildings, are used for heating of cooling purposes. Although the absolute values of deformations and temperature gradients are low or moderate, the entire setting can be influenced by thermo-hydro-mechanical ... 詳細を見る

Transient Simulation of the Electrolyte Flow in a Closed Device for Precise Electrochemical Machining

M. Hackert-Oschätzchen[1], M. Penzel[1], M. Kowalick[1], G. Meichsner[2], A. Schubert[1,2]
[1]Professorship Micromanufacturing Technology, Technische Universität Chemnitz, Chemnitz, Germany
[2]Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

Precise electrochemical machining (PEM) is an innovative machining technology which results from further development of the electrochemical sinking. PEM works with pulsed low frequency direct current and oscillation of the tool electrode. As part of the project ‘Electrochemical machining ... 詳細を見る

Analysis of the Electrochemical Removal of Aluminum Matrix Composites Using Multiphysics Simulation

M. Hackert-Oschätzchen[1], N.Lehnert[1], M. Kowalick[1], G. Meichsner[2], A. Schubert[1,2]

[2]Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

In the Collaborative Research Centre 692 at TU Chemnitz several academic institutions work on aluminum matrix composites (AMCs). These materials consist of an aluminum matrix, which is reinforced by SiC or Al2O3 particles with dimensions less or equal 1 µm. One main task is finishing ... 詳細を見る

Implementation of COMSOL Multiphysics® in Simulink® S-Functions, Revisited

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

COMSOL Multiphysics® has standard facilities to export models to SimuLink®. Normally, the standard export works well if the solvers, available in SimuLink, can handle the problem. However, if a model in COMSOL Multiphysics® needs special solvers, for example airflow or other non-linear ... 詳細を見る

3D Modeling of All-Superconducting Synchronous Electric Machine by Finite Element Method

D. Hu[1], M. Ainslie[1], J. Zou[1], D. Cardwell[1]
[1]Bulk Superconductivity Group, Department of Engineering, University of Cambridge, Cambridge, UK

This paper presents the electromagnetic analysis of an all-superconducting synchronous electric machine, focusing on AC loss calculations in high temperature superconducting (HTS) coils. The numerical analyses of two 3D models are shown, including the model of the machine and its HTS ... 詳細を見る
