Effects of Flow and Diffusion on Blood Coagulation in Platelet Poor Plasma: a Two-way Coupling Between Hemodynamics and Biochemistry

D. Magnabosco[1,2], H. van Ooijen[2], B. Bakker[2], R. van den Ham[2]
[1]Politecnico di Milano, Milan, Italy
[2]Philips Research, Eindhoven, The Netherlands

Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and ... Read More

Fluid Structure Interaction of Arch Dam on Full Reservoir Level under Seismic Loading

R. Manikandan[1], R. Jayashiri [1], R. Indumathi [1], J. Archana [1],
[1] Dhirajlal Gandhi College of Technology, Salem, Tamil Nadu, India

The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid ... Read More

Modeling Microwave Heating During Batch Processing of a Liquid Sample in a Single Mode Cavity

S. Curet [1], F. Bellicanta Begnini [1], O. Rouaud [1], L. Boillereaux [1]
[1] L’UNAM Université, ONIRIS, CNRS, GEPEA, Nantes, France

The use of microwaves for heating purposes of dielectric materials is encountered in many industrial applications (food processing, chemistry, material engineering and medical applications). In most of these thermal applications, the prediction of the temperature evolution within the ... Read More

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 ... Read More

Rheological Behaviour of Single–Phase Non-Newtonian Polymer Solution in Complex Pore Geometry: A Simulation Approach

P. Idahosa[1], G. Oluyemi[2], R. Prabhu[2], B. Oyeneyin[2]
[1]IDEAS Research Institute/School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.
[2]School of Engineering, Robert Gordon University, Aberdeen, United Kingdom.

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete ... Read More

Design Improvement Of A Bench-Scale Nanofiltration Device By CFD Study

B. Balannec[1,2], T. Renouard[1,2], and F.Cortès-Juan[3]
[1]Université de Rennes 1-ENSCR-CNRS, France
[2]Université européenne de Bretagne, France
[3]Universidad Politécnica de Valencia, Spain

Feasibility studies in the field of membrane processes are generally first carried out with bench-scale membrane filtration cells. These small laboratory cells also allow evaluating the influence of operational parameters and the membrane performances. Smart design of the cell geometry ... Read More

FEA Simulation of Passive Ferrofluid Cooling Systems

Z. Fang[1,2], R. O'Handley[2], Y. Liu[2], and M. Yang[2,3]
[1]Pennsylvania State University, University Park, PA, USA
[2]Ferro Solutions Inc., Woburn, MA, USA
[3]Massachusetts Institute of Technology, Cambridge, MA, USA

Here we investigate a promising passive cooling method through making advantage of the unique properties of ferrofluid. When a magnetic dipole or a permanent magnet is put at the hot side of a system, it will attract the cold ferrofluid to the hot place and displace the hot ferrofluid ... Read More

Mathematical Model of Blood Flow in Carotid Bifurcation

E. Muraca[1], V. Gramigna[1], and G. Fragomeni[1]
[1]Department of Experimental Medicine and Clinic, Magna Graecia University of Catanzaro, Catanzaro, Italy

The goal of this research is to provide the medical staff with a numerical system assessment of wall shear stress in carotid bifurcation. Through this model, it will be fundamental to investigate the stress state properties of the surface in contact between the plaque and the artery, and ... Read More

Modeling of a DBD Reactor for the Treatment of VOC

L. Braci[1], S. Ognier[1], and S. Cavadias[1]
[1]Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, Ecole Nationale Supérieure de Chimie de Paris, University Pierre et Marie Curie, Paris, France

Non-thermal plasma, generated in atmospheric pressure discharges, has been investigated in our laboratory in order to treat highly diluted (300 ppm to 1000 ppm) volatile pollutant. The collision of electrons created in the discharge with atmospheric air, leads to the formation of ... Read More

Flow of Dry Foam in a Pipe

M. Divakaran[1], S. K. Gupta[1]
[1]Department of Chemical Engineering, Indian Institute of Science, Bangalore, Karnataka, India

Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group ... Read More
