[1]The University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, United Kingdom

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human ... En savoir plus

Role of the Diffusion Current in Nonequilibrium Modeling of Welding Arcs

M. Baeva[1]
[1]INP Greifswald e.V., Greifswald, Germany

2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... En savoir plus

Fluid-Structure Interaction Analysis of a Peristaltic Pump

N. Elabbasi, J. Bergstrom, and S. Brown
Veryst Engineering, LLC.
Needham, MA

Peristaltic pumping is an inherently nonlinear multiphysics problem where the deformation of the tube and the pumped fluid are strongly coupled. We used COMSOL Multiphysics to investigate the performance of a 180 degree rotary peristaltic pump with two metallic rollers, and an ... En savoir plus

A Lesson in Cartilage Therapy: Do Chondrocytes Utilize Mechanical Energy from Exercise for Cell Maintenance and Growth?

A. Miller [1], H. Viljoen [1], A. Chama [2], T. Louw [2],
[1] Department of Chemical and Biomolecular Engineering, University of Nebraska - Lincoln, Lincoln, NE, USA
[2] Department of Chemical Engineering, Stellenbosch University, Stellenbosch, South Africa

Using COMSOL Multiphysics® Acoustics Module: Chondrocytes modeled attached to a plane (to mimic in vivo constraints) are shown to resonate near 5MHz. At resonance, the mechanical energy density in the nucleus is two times higher than in the cytoplasm. Impact exercise is modeled as ... En savoir plus

Modelling Flow through Fractures in Porous Media

E. Holzbecher[1], W.L. Wah[1], and M-S. Litz[2]
[1]Georg-August Universität Göttingen, Germany
[2]Freie Universität Berlin, Germany

There are various alternative options concerning modeling fluid flow within fractures in porous media. We give a general overview, with remarks concerning the modeling using COMSOL Multiphysics. Moreover we define and study two test cases for intercomparison. Finally for one of the ... En savoir plus

Numerical Modeling of Falling Aluminum Particle Oxidation in Air

A. Davidy
Israel Military Industry, Ramat-Hasharon, Israel

Because of its high enthalpy of combustion, aluminum has been added to energetic materials. In this paper, a two dimension thermal model is developed and assessed to describe the interrelated processes of Aluminum particle oxidation by using the software COMSOL Multiphysics. The thermal ...

Simulation and Performance of Pulsed Pipe Flow Mixing in Non-Newtonian Liquid Dispersion Media

T. Koiranen[1], J. Tamminen[1], A. Häkkinen[1]
[1]LUT Chemtech, Lappeenranta University of Technology, Lappeenranta, Finland

A non-newtonian oil dispersion in a pulsed flow pipe system was mixed in a circulation loop pipe with custom-made static mixers. The rotor-pump was used in a non-pulsed flow circulation, and diaphragm pump for pulsed flow circulation. Modeling was done using COMSOL Multiphysics® 4.3b. ... En savoir plus

Aggregation Kinetics of Colloidal Nanoparticles in a Circulating Microfluidic Cavity
