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 ... En savoir plus

Mathematical Modeling Of Traveling-Wave Electroosmotic Micropumps By Using Of The Weak Form

J. Hrdlicka, P. Cervenka, and D. Snita
Institute of Chemical Technology Prague, Prague, Czech Republic

This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and ... En savoir plus

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... En savoir plus

A Simplified Numerical Model for Simulating Sliding Door and Surgical Staff Movement in an Operating Theater

C. Balocco[1]
[1]Dipartimento di Energetica, Università di Firenze, Firenze, Italy

This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... En savoir plus

Simulating A Fan For Industrial Ventilation

G. Argentini
Riello Burners, Italy

This work talks on simulation of a ventilating structure for an industrial burner. The mathematical model is based on the frozen-rotor technique, and the numerical simulation is used for resolution of fluid dynamics equations for the air flow into the rotating wheel and into the static ...

Applicability of the Fracture Flow Interface to the Analysis of Piping in Granular Material

S. Bersan[1], C. Jommi[2], A. Koelewijn[3], P. Simonini[1]
[1]University of Padua, Padua, Italy
[2]Delft University of Technology, Delft, The Netherlands
[3]Deltares, Delft, The Netherlands

Piping is a kind of internal erosion that occurs under water retaining structures lying on a sandy soil. In an attempt to reproduce the growth of erosion channels in sand, a small scale physical model has been set up in the laboratory and a finite element model that reproduces the ... En savoir plus

Shape Optimization of Electric and Magnetic System using Level Set Technique and Sensitivity Analysis

Y. Sun Kim, A. Weddemann, J. Jadidian, S. Khushrushahi, and M. Zahn
Dept. of Electrical Engineering and Computer Science
MIT
Cambridge, MA

The classical optimization method has been applied to many design problems for electromagnetic systems. One of its major difficulties is related to meshing problems arising from shape modifications. In order to circumvent these kinds of technical difficulties with moving mesh problems, ... En savoir plus

Long Term Performance Of Borehole Heat Exchanger Fields With Groundwater Movement

S. Lazzari, A. Priarone, and E. Zanchini
DIENCA, University of Bologna, Bologna, Italy

A numerical investigation of the long-term performance of double U-tube borehole heat exchanger (BHE) fields, in the case of non-negligible effects of groundwater movement, is performed by means of COMSOL Multiphysics. Two time periodic heat loads, with a period of one year, are studied: ... En savoir plus
