Accuracy of Fully Coupled Loudspeaker Simulation Using COMSOL

M. Hedges[1][2] and Y.W. Lam[1]
[1]Acoustics Research Centre, School of Computing, Science & Engineering, University of Salford, Salford, United Kingdom
[2]Monitor Audio Ltd., Rayleigh, Essex, United Kingdom

Loudspeaker simulation is used to inform the designer as to the performance of a design. In recent years the Finite Element Method (FEM) has been used to model the mechanical and acoustical attributes of a loudspeaker with varying success. This paper shows how a model that incorporates ... En savoir plus

Numerical Simulation of Warm-Air Drying of Mexican Softwood (Pinus Pseudostrobus)

S. Sandoval Torres[1], E. Hernández-Bautista[1], J. Rodríguez-Ramírez[1], A. Carrillo Parra[2]
[1]Instituto Politécnico Nacional, CIIDIR, Oaxaca, Mexico
[2]Facultad de Ciencias Forestales, Universidad Autónoma de Nuevo León, Linares, N.L. México

In this work, the numerical simulation of Mexican softwood (Pinus pesudostrobus) drying is presented by solving a physics-based model. The model was developed by considering the heat and mass transport and the representative elementary volume, which involves the solid, liquid and gas ... En savoir plus

Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum

M. Bachmann[1], V. Avilov[1], A. Gumenyuk[1], M. Rethmeier[1]
[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the ... En savoir plus

Computational Modeling to Study the Treatment of Cardiac Arrhythmias using Radiofrequency Ablation

A. González-Suárez[1], M. Trujillo[2], J. Koruth[3], A. D'Avila[3], E. Berjano[1]
[1]Biomedical Synergy, Electronic Engineering Department,Universitat Politècnica de Valencia, Valencia, Spain
[2]Instituto Universitario de Matemática Pura y Aplicada, Universitat Politècnica de Valencia, Valencia, Spain
[3]Helmsley Cardiac Electrophysiology Center, Mt SinaiMedicalCenter and School of Medicine, New York, NY, USA

Previous studies proposed using bipolar radiofrequency ablation across two catheters placed on opposing surfaces of the ventricular wall to create transmural lesions. 2D and 3D models were built and solved with COMSOL Multiphysics software. With these models, it was possible to study the ... En savoir plus

Optimization of the Design of a GEM Tracker Based on Gas Flow Simulations with COMSOL
