Using COMSOL Multiphysics for Modeling of Musculoskeletal Biomechanics

R. L. Spilker
Department of Biomedical Engineering, Rensselaer Polytechnic Institute, New York, USA

In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft ... En savoir plus

Parameter Extraction and Support-Loss in MEMS Resonators

Peter Steeneken
Project Leader
RF MEMS Research Group
NXP Semiconductors
Eindhoven, The Netherlands

In this paper it is shown how the equivalent circuit parameters of a MEMS resonator can be simply obtained from an eigenfrequency simulation. Additionally, it is demonstrated that the Q-factor as a result of support losses in a MEMS resonator can be determined using a matched boundary ... En savoir plus

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... En savoir plus

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

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

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus

Modeling the ELENA Electron Cooler with COMSOL Multiphysics® Software

G. Tranquille[1]
[1]CERN, Geneva, Switzerland

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA ... En savoir plus

Modeling an Adsorption Process in a Shell-and-Tube-Heat-Exchanger-Type Adsorber

G. Salazar Duarte[1], B. Schürer[1], C. Voss[1], D. Bathen[2]
[1]Linde AG, Munich, Germany
[2]Universität Duisburg-Essen, Duisburg, Germany

Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) are commonly used for separation/purification of gas mixtures in industrial processes. The cycle time of industrial TSA processes usually ranges from several hours to days. The reason for this long cycle time is the ... En savoir plus

Numerical Investigation of Heat Transfer of Aluminum Metal Foam Subjected to Pulsating Flow

A. Bayomy[1], M. Z. Saghir[1]
[1]Ryerson University, Toronto, ON, Canada

The rapid development of electronic devices leads to more demand for efficient cooling techniques. Porous media represent a convincing passive cooling enhancer due to its large contact surface area to volume ratio and intense mixing of ﬂuid ﬂow. In the present work, numerical studies ...

An Automatic Modeling Approach for Optimized Positioning of an Electrostimulative Implant in the Human Femoral Head

Y. Su[1], D. Kluess[1], W. Mittelmeier[1], M. Ellenrieder[1], U. van Rienen[2], R. Bader[1]
[1]Department of Orthopaedics, University of Rostock, Rostock, Germany
[2]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head ... En savoir plus

Acoustical Analysis of a Home Recording Studio

K. Anderson[1], A. Smith[1], D. Forgette[1]
[1]Mechanical Engineering, California State Polytechnic University at Pomona, Nonlinear FEM/CFD Multiphysics Simulation Lab, Pomona, CA, USA

In this poster the acoustic analysis of a small home recording studio is presented.. Figure 1 illustrates the recording studio room which was simulated using the COMSOL Multiphysics® software with the Acoustics Module [1]. The propagation of sound is modeled as pressure waves in which ... En savoir plus

Solid Oxide Fuel Cell Material Structure Grading in the Direction Normal to the Electrode/Electrolyte Interface Using COMSOL Multiphysics®

M. Andersson[1], B. Sundén[1]
[1]Department of Energy Sciences, Lund University, Lund, Sweden

Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics® is used to describe an intermediate temperature solid oxide fuel ... En savoir plus
