Multiphysics Analysis of Electromagnetic Flow Valve

J. S. Crompton [1], K. Koppenhoefer [1], S. Yushanov [1],
[1] AltaSim Technologies, Columbus, OH, USA

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... En savoir plus

Heat Propagation Improvement in YBCO-Coated Conductors for Superconducting Fault Current Limiters

D. M. Djokic[1], L. Antognazza[1], M. Abplanalp[2], M. Decroux[1]
[1]DPMC, University of Geneva, Geneva, Switzerland
[2]ABB Corporate Research Centre, Dättwil, Switzerland

YBCO Coated Conductors (CCs), used for applications in Resistive Superconducting Fault Current Limiters (RSFCLs), are known to have insufficiently high Normal Zone Propagation Velocity (NZPV) during quench events. The improvement can be made by enhancing the thermal conductivity of YBCO ... En savoir plus

Mean Flow Augmented Acoustics in Rocket Systems

S. Fischbach[1]
[1]NASA Marshall Space Flight Center / Jacobs ESSSA Group, Huntsville, AL, USA

Combustion instability in solid rocket motors and liquid engines has long been a subject of concern. Recent advances in energy based modeling of combustion instabilities require accurate determination of acoustic frequencies and mode-shapes. Of particular interest is the acoustic mean ...

Analysis Of Particle Trajectories For Magnetic Drug Targeting

A. Heidsieck, and B. Gleich
Zentralinstitut für Medizintechnik, TU München, München, Germany

The technique of magnetic drug targeting binds genetic material or drugs to superparamagnetic nanoparticles and accumulates them via an external magnetic field in a target region. However, it is still a challenge for this approach to succeed in areas with high flow rates, like the aorta ... En savoir plus

Simulation of Piezoelectrically Actuated Drug Delivery Device for Biomedical Application

J. Dsa[1], Manisha[1], M. Goswami [1], B.R Singh [1],
[1] Indian Institute of information technology Allahabad, Allahabad, Uttar Pradesh, India

We have developed a piezoelectrically controlled MEMS drug delivery device for on-demand release of defined quantities of drug. A drug-loaded micro reservoir (∅6mm×550µm) is sealed by A membrane placed over the drug reservoir on which the piezoelectric material is deposited. On ... En savoir plus

Thermal Performance of the New Bioclimatic Hall of the Historical Hospital in Florence

C. Balocco, and E. Marmonti
Dipartimento di Energetica “Sergio Stecco”
Università degli Studi di Firenze
Firenze, Italy

The main aim of the present work is the study of the thermal and energy performances of the new hall of the Old St.Maria Nuova Hospital in the center of Florence (Italy). Transient simulations were carried out of the 3D model of the hall to analyse the air flow patterns, distribution and ... En savoir plus

Investigation on Sensor Fault Effects of Piezoelectric Transducers on Wave Propagation and Impedance Measurements

I. Buethe[1], C.-P. Fritzen[1]
[1]University of Siegen, Institute of Mechanics and Control Engineering-Mechatronics, Siegen, Germany

For active Structural Health Monitoring (SHM), one popular sensor type is the piezoelectric wafer active sensor (PWAS) due to its multi-purpose application as actuator and sensor and its low cost. It is used to generate a wave field, which interacts with the structure and is recorded by ... En savoir plus

Numerical Aspects of the Implementation of Artificial Boundary Conditions for Laminar Fluid-Structure Interactions

C. Boeckle[1], P. Wittwer[1]
[1]University of Geneva, Geneva, Switzerland

We discuss the implementation of artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a finite domain for numerical purposes, artificial boundaries appear. We present an ... En savoir plus

Assessment of COMSOL Capabilities to Analyse the Thermo- Hydrodynamic Behaviour of the MSR Core

A. Cammi[1], V. Di Marcello[1], C. Fiorina[1], and L. Luzzi[1]

[1]Nuclear Engineering Division, Department of Energy, Politecnico di Milano, Milano, Italy

The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both ... En savoir plus

Numerical Simulation of Magnetic Drug Targeting with Flow – Structural Interaction in an Arterial Branching Region of Interest

A. Morega, A. Dobre, and M. Morega
University Politehnica of Bucharest, Bucharest, Romania

We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image ... En savoir plus
