Simulation of a Piezoelectric Catheter-Based Acoustic Ablation Device

M. Gobran¹, N.Elabbasi², J. Ransley²
¹Worcester Polytechnic Institute, Worcester, MA, USA
²Veryst Engineering LLC., Needham, MA, USA

Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... En savoir plus

To a Fluidic Diode for Biomedical Application

A. Slami [1], [2], V. Tishkova [2], R. Grossier [2], M. Lagaize [2], S. Veesler [2], S. Sofiane [3], N. Candoni [2],
[1] Biomedical Engineering laboratory, University of Tlemcen, Algeria and Aix Marseille Univ, CNRS, Centre Interdisciplinaire de Nanoscience de Marseille (CINaM), Marseille, France
[2] Aix Marseille Univ, CNRS, Centre Interdisciplinaire de Nanoscience de Marseille (CINaM), Marseille, France
[3] Biomedical Engineering laboratory, University of Tlemcen, Algeria

This work is focused on Micropump optimization for drug delivery application. Diabetes is one of the widely pervaded diseases. Among the side effects of hyperglycemia is the weakness of the whole body, so the patient will be unable to inject manually the drug. Therefore, Micropumps are ... En savoir plus

Simulation of Fluid Flow in an Artificial Soiling Device

E. Klimm [1], S. Kochersperger [1], K.-A. Weiss [1],
[1] Fraunhofer Institute for Solar Energy Systems, Freiburg, Germany

Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... En savoir plus

A Trapping Mechanism of a Single-Particle Inside a Triangular Microwell

Phakpoom Yingprathanphon [1],
[1] Chulalongkorn University, Thailand

Transplantation of organs and tissues remains the solution for repair of damaged tissue, yet the shortage of donor human organs for transplant is another issue as well. In the field of regenerative medicine, several regenerative technologies have recently been developed using various ... En savoir plus

Impact of Electro-Convection (EC) on Heat Transfer in Liquid-Filled Containers

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... En savoir plus

Influence of Inlet Fluctuations on the Development of The Turbulent Two-Stream Mixing Layer

J. Tawfik, and R. Arimilli
The University of Tennessee, Knoxville, TN, USA

The finite element method applied to the k-epsilon turbulence model is used to investigate the two-stream turbulent mixing layer. Whereas the model is known as one of the most popular of the turbulence models to date, the model has yet to be applied to the classical mixing layer problem ... En savoir plus

A Plasma Torch Model

B. Chiné [1],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica

Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

Impact Simulation of Extreme Wind Generated Missiles on Radioactive Waste Storage Facilities

G. Barbella[1]
[1]Sogin SpA, Roma, Italy

The structural design of temporary storage facilities for radioactive waste generally requires the fulfillment of highly severe performance criteria if compared to conventional buildings. This work focuses on the study of the behavior of a steel door subject to the impact of extreme wind ... En savoir plus

Numerical simulation of a hybrid refrigerator combining GM gas expansion with magnetic refrigeration

郭小惠 [1], 李珂 [1], 戴巍 [1], 高新强 [1], 沈俊 [1],
[1] 中国科学院理化技术研究所，北京

Abstract: Gifford-McMahon (GM) refrigerator based on gas expansion effect can provide a cooling temperature below 4.2 K, which is widely used to cool superconducting magnets for applications such as magnetic resonance imaging and to provide low temperature environment for condensed ...

Deformation Behavior Of A Liquid Droplet Impacting A Solid Surface

S. Oukach[1], M. Elganaoui[1], B. Pateyron[1], and H. Hamdi[2]
[1]Laboratoire des Sciences des Procèdes Céramiques et de Traitements de Surface SPCTS, Limoges, France
[2]Laboratoire de Mécanique des Fluides et Energétique LMFE, Marrakech, Morocco

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good ... En savoir plus
