Non-Newtonian Hemodynamics and Shear Stress Distribution in Three Dimensional Model of Healthy and Stented Coronary Artery Bifurcation

M.M. Zarandi[1], R. Mongrain[1], and O.F. Bertrand[2]
[1]McGill University, Montreal, QC, Canada
[2]Laval University Quebec City, QC, Canada

In this paper, a three-dimensional model of the coronary artery bifurcation is developed and physiological flow in the both healthy and stented coronary artery bifurcation is modeled using COMSOL Multiphysics. Wall shear stress induced by endovascular stents in the coronary artery ... 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

Entropic Evaluation of Dean Flow Micromixers

P. S. Fodor[1], M. Kaufman[1]
[1]Cleveland State University, Cleveland, OH, USA

In this work we investigate computationally the use of spiral channels at Reynolds numbers from 25 to 900 as a mixing structure (Figure 1) using COMSOL Multiphysics, the CFD Module, and the Chemical Species Transport physics. In this system, the centrifugal forces experienced by the ... En savoir plus

Handling Tessellated Free Shape Objects with a Morphing Mesh Procedure in COMSOL Multiphysics^®

P. Franciosa[1] and S. Gerbino[2]
[1]Faculty of Engineering, University of Naples Federico II, Napoli, Italy
[2]Faculty of Engineering, University of Molise, Campobasso, Italy

Tessellated models are more and more used in several engineering fields. The need to use such models to quickly perform computer simulations related to coupled physical phenomena, implies the use of dedicated software, allowing to solve, into an integrated environment, multiphysics ...

Design and Simulation of a Microscale Magnetophoretic Device for the Separation of Nucleated Fetal Red Blood Cells from Maternal Blood

G. Schiavone[1], D.M. Kavanagh[2], and M.P.Y Desmulliez[2]

[1]Politecnico di Torino, Torino, Italy
[2]MIcroSystems Engineering Centre, School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh, Scotland, United Kingdom

Intense research has been carried out into methods that aim at harvesting fetal cells from maternal blood as substitutes to amniocentesis and chorionic villus sampling. This work focuses on the separation of fetal nucleated red blood cells from the maternal circulation based on their ... En savoir plus

Modeling a Novel Shallow Ground Heat Exchanger

M. Bottarelli[1], M. Bortoloni[1]
[1]Università degli Studi di Ferrara, Dipartimento di Architettura, Ferrara, Italia

Ground Heat Exchangers (GHXs) are rarely installed horizontally in linked ground source heat pumps used for space conditioning, because their energetic performance is lower than in the vertical solution. However, the horizontal one holds several advantages: it is easy to carry out and ... En savoir plus

Using COMSOL Multiphysics^® for Biomechanical Analysis of Stent Technology in Cerebral Aneurysms

J. Rasmussen[1], M.S. Enevoldsen[1], J. Thyregod[2], and K-A. Henneberg[1]
[1]Department of Electrical Engineering, Technical University of Denmark, Kgs. Lyngby, Denmark
[2]COOK Medical Europe, Bjaeverskov, Denmark

This work presents new Fluid-Structure Interaction (FSI) models in both 2D and 3D of the effect of using vascular stents as treatment of cerebral berry aneurysms. The stent is positioned inside the cerebral artery covering the neck of the aneurysm. The stent is expected to alter the ... En savoir plus

Using Computational Fluid Dynamics Model to Predict Changes in Velocity properties in Stented Carotid Artery

S. Vaidehi, and A. Ritter
Stevens Institute of Technolgy, Hoboken, NJ, USA

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
