Simulation of Electrodynamic Planar Loudspeaker (EDPL) with COMSOL Multiphysics® Software

M. Asgarisabet [1,2], R. Czapla [2], J. Krueger [2], B. Sterling [2],
[1] Michigan Technological University, Houghton, MI, USA
[2] HARMAN International, Detroit, MI, USA

A simulation of an electrodynamic planar loudspeaker (EDPL) has been developed in this study with the COMSOL Multiphysics® software. Using the simulated model, effect of different parts has been studied to improve the performance. The locations of the coil and magnets have been obtained ... En savoir plus

Study of Energy Transfer Mechanism for a Synchrotron X-ray Gas Absorber with COMSOL Multiphysics

A. Martín Ortega [1], Y. Dabin [1], T. Minea [2], A. Lacoste [3]
[1] ESRF, Grenoble, France
[2] LPGP, Université Paris-Sud XI, Orsay, France
[3] LPSC, Université Joseph Fourier, Grenoble, France

The high power of X-ray beam delivered by synchrotrons and free electron lasers, up to 240 W/mm2, requires heat load management solutions to obtain the best performance from the optical elements which will shape the beam for its use in the experimental stations [1]. One solution is the ... En savoir plus

Sub-Millimetric Vacuum Electron Gun Design and Characterization

A. Leggieri[1], G. Ulisse[1], F. Di Paolo[1], F. Di Paolo[1], A. Di Carlo[1]
[1]University of Rome "Tor Vergata" - Department of Electronic Engineering, Rome, Italy

This paper presents the design of an electron gun that could be employed for vacuum tubes operating in the THz range. In this context, vacuum tubes one of the main difficulties in the realization of THz vacuum tube is the design and the realization of the electron gun. Since the ... En savoir plus

3D Modeling of Urban Areas for Built Environment Applications Using COMSOL

J. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent ... En savoir plus

Numerical Investigation Of Non-Newtonian Emulsion Formation At Microfluidics T-Junction

W. V. Loong [1]
[1] SEGi University, Malaysia

The main focus of the present study is the parametric investigation of the influence of viscosity on breakup dynamics of the non-Newtonian sodium carboxymethylcellulose (CMC) droplets. It presents the numerical simulations of the fluid dynamics of CMC droplets with shear-thinning ... En savoir plus

Temperature Gradients Controlled Broadband Acoustic Omnidirectional Absorber

F. Qian[1], L. Quan[1], X. Liu[1]
[1]Institute of Acoustics and School of Physics, Nanjing University, Nanjing, China

Previous research into acoustic omnidirectional absorber (AOA) has shown the feasibility of forming acoustic black hole to guide the incident wave into the central absorptive cavity. However, major restrictions to practical applications exist due to complexity of designing metamaterials ... En savoir plus

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... En savoir plus

Modeling of Energy Efficient Continuous Sterilisation of ABP from Food Wastes

S. Dalrymple[1], R. Heslop[1]
[1]C-Tech Innovation Ltd. , Capenhurst, United Kingdom

Ohmic heating is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content which would ... En savoir plus

Easy Evaluation of Streamer Discharge Criteria

G. Eriksson[1]
[1]ABB, Corporate Research, Västerås, Sweden

An easily implemented method is devised, where analytical criteria for the occurrence of streamer discharges in strong electric fields are evaluated. This is highly useful when designing high voltage power transmission systems and components where the insulation is provided by a gas, e ... En savoir plus

Modeling of a Magnetocaloric System for Electric Vehicles

A. Noume[1], C. Vasile[1], M. Risser[1]
[1]National Institute of Applied Science (INSA), Strasbourg, France

In automotive industry, regardless the type of engine we use, heating and air-conditioning is responsible for the highest energy consumption among all the auxiliary systems all over the year. For conventional vehicles with thermal engines, the heating of the internal space is easy ... En savoir plus
