Multiphysics Simulation of a Self-heating Paraffin Membrane Microactuator

P. Lazarou[1], C. Rotinat[1]
[1]CEA LIST/DIASI/LRI, Paris, France

A grand variety of microactuator technologies and demonstrators has been introduced during the last years. Of particular interest are the microactuators based on phase change materials and especially paraffin wax, which can volumetrically expand up to 15%, providing high force actuation. ...

[3] Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

Precise electrochemical machining (PEM) is a non-conventional machining technology, based on anodic dissolution of metallic work-pieces. In this study an additional extension of the precise electrochemical machining with a precise angle-controlled cylinder positioning is aimed. Due to ... En savoir plus

Multiphysics Design of a Klystron Buncher

A. Leggieri [1], D. Passi [1], F. Di Paolo [1], G. Saggio [1]
[1] University of Rome, Rome, Italy

The Multiphysics design of a 130 GHz klystron Buncher cavity is described in this paper. In this high frequency range, dimensions are critical and expose the device to multiple physics effects, due to the power dissipations, affecting the electromagnetic performances. The proposed device ... En savoir plus

Interface Phenomena for a Multifunctional Air-Water Micro-Particle Collecting and Filtering System

E. Lacatus [1], A. Tudor [1], G. C. Alecu [1],
[1] Polytechnic University of Bucharest, Romania

The confinement clean rooms used in industry are susceptible to higher count of particles per cubic meter of air after the usual work program. To decrease the economic and technological effects of particle concentration a micro-cleaning device was elaborated. A first approach of a 3D ... En savoir plus

Thermomechanical Effects of the Packaging Molding Process on the Chip in Integrated Circuits

N. Semmar[1], M. Fournier[1], P. S. Alleaume [2], A. Seigneurin [3], , ,
[1]GREMI-UMR7344, CNRS/University of Orléans, Orléans, France
[2]Collegium Sciences et Techniques, Orléans, France
[3]ST Microelectronics Tours SAS, Tours, France

Usually, in integrated circuits, the chip is brazed on leadframe and then, a polymer resin is molded around to create the packaging. On the first hand, the molding process at high temperatures will induce thermomechanical stress on the chip. As the leadframe, the chip and the braze have ... En savoir plus

Drag Fluctuations of a Fully Deployed Flow Actuator Embedded Inside Turbulent Boundary Layer Flow

Dr. A. Elzawawy[1]
[1]Engineering & Technology Department, Vaughn College of Aeronautics & Technology, Flushing, NY, USA

Introduction: In this work, a CFD model of 2D flow around a fully deployed flow actuator was developed using COMSOL Multiphysics® software and the CFD Module. The results of COMSOL modeling is also compared with the experimental data of the same dimensions actuator. The 100mmX2mm ... En savoir plus
