[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

Pore-Scale Simulation of Two-Phase Flow with Heat Transfer Through Dual-Permeability Porous Medium

H.A. Akhlaghi Amiri[1], A.A. Hamouda[1]
[1]University of Stavanger, Stavanger, Rogaland, Norway

This paper addresses one of the major challenges in water-flooded oil reservoirs, which is early water breakthrough due to the presence of high permeable layers in the media. COMSOL Multiphysics is used to model two phase (water and oil) flow in dual-permeability porous medium at micro ... En savoir plus

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

Simulation Study of High Frequency Pulsed DC Discharges in Nitrogen

L. Tong [1],
[1] Keisoku Engineering System Co., Ltd., Tokyo, Japan

Pulsed DC technology has led to the design of cost-effective deposition systems and to improved film properties, compared to conventional rf systems. In this work, a two-dimensional finite element model is used to investigate the high frequency pulsed DC discharges in nitrogen. The study ... En savoir plus

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models

[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... En savoir plus

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

Novel Automated Software System for Arcing Simulation in Spacecraft On-Board Electronics

[1] Institute of High Current Electronics, Tomsk, Russia
[2] Tomsk State University of Control Systems and Radioelectronics, Tomsk, Russia

In our project, we propose an innovative software solution to the problem of electrical arcing risk prediction in high-voltage on-board electronic equipment intended for long-term self-contained use, e.g. in spacecraft conditions. It completely based on so-called “decomposition” approach ... 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

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
