From customer requirement to product requirement with COMSOL
Anders B Nilsson graduated M. Sc. in engineering physics from Lund University in Sweden. He has been working in the R&D department at BD Medical as principal engineer and project leader since 2005. He uses COMSOL for a wide range of functions, such as early concept development and ... En savoir plus
An MHD Modeling of High-Temperature SiC Solution Growth
Despite its real advantages compare to seeded sublimation growth, SiC solution growth has never given convincing results. The difficulty of stabilizing the growth front, and thus avoiding any polycrystal formation results from a poor description and understanding of the coupled phenomena ... En savoir plus
Using Computational Fluid Dynamics Model to Predict Changes in Velocity properties in Stented Carotid Artery
Atherosclerosis is a disease that narrows, thickens, hardens and restructures a blood vessel due to substantial plaque deposit. In the Carotid Artery, the decision to treat using endarterectomy and stenting is determined by the velocity as measured by Doppler flow in the common Carotid ... En savoir plus
Electro-Thermo-Mechanical Finite Element Modeling to Investigate the Reliability of Automotive MOSFET Transistor
3D electro-thermo-mechanical finite element model of power vertical MOSFET used in the automotive industry is presented in this paper. The presented paper is a qualitative study of power device results from electro-thermo-mechanical simulation. This study particularly interested in the ... En savoir plus
A Model of Gas Bubble Growth by COMSOL Multiphysics
We use COMSOL Multiphysics to model a gas bubble expansion in a viscous liquid initially at rest, a very common system for lightweight foamed materials from metal production and polymer processing. Modelling and simulation of foam processing during the production step involves many ... En savoir plus
Numerical Simulation of Magnetic Drug Targeting with Flow – Structural Interaction in an Arterial Branching Region of Interest
We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image ... En savoir plus
Simulation of Laser-Material Interactions for Dynamic Transmission Electron Microscopy Experiments
The Dynamic Transmission Electron Microscope (DTEM) at Lawrence Livermore National Laboratory is a unique instrument able to capture images of fast-evolving microstructure with exposure times of only 15 ns. This is more than six orders of magnitude faster than conventional in situ ... En savoir plus
Erosion Of Buffer Caused By Groundwater Leakages Based On ESM-Application
In this work the issue of saturation phase erosion caused by groundwater leakages was approached both experimentally and computationally by employing COMSOL\'s Earth Science Module. We evaluated the total mass of eroded bentonite out of a cylindrical erosion channel both numerically and ... En savoir plus
Beam Structure As an Acoustic Wave Sensor: A Study of the Effect of Sensor Design on Its Sensitivity to Noise
The detection and identification of the location of a sound source is commonly done using arrays of microphones. A recent new alternative approach has been proposed which involves the use of continuous structures, such as beams or plates, as acoustic wave sensors. The sound wave ... En savoir plus
Heat Flux Predictions for a 3-D Compost Model
A 3-D model for compost was constructed taking as geometry basis a truncated cone, with dimensions of 4 m radius and 3 m height; in this structure an energy balance is applied for a two phase system (solid-air). Compost energy processes are modeled using COMSOL with a modified heat ... En savoir plus
