Design, Fabrication and Simulation of Microchannel Network for MEMS

V. Jain[1], A. K. Sharma[2], P. Kumar[2]
[1]Thapar University, Patiala, Punjab, India
[2]Indian Institute of Technology Roorkee, Roorkee, Uttar Pradesh, India

The greatest challenge being faced for realization of Micro-Electro Mechanical System (MEMS) technology is the lack of a simple, quick and reliable method for the fabrication of 3-D microchannel in the range of micrometers. A novel fabrication technique which opens possibilities for the ... En savoir plus

Numerical Study on Shear Horizontal Electromagnetic Acoustic Transducers for Generation of Ultrasonic Guided Waves for Absorber Tubes used in Concentrated Solar Plants

L. Cheng[1], A. Mohimi[1], M. Kogia[1], V. Kappatos[1], C. Selcuk[1], T.-H. Gan[1]
[1]Brunel Innovation Centre, Brunel University, Uxbridge, UK

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential ... En savoir plus

3D Modeling of Urban Areas for Built Environment Applications Using COMSOL

J. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent ... En savoir plus

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... En savoir plus

Numerical Quasi Stationary and Transient Analysis of Annular Linear Electromagnetic Induction Pump

L. Goldsteins[1], L. Buligins[2], Y. Fautrelle[3], C. Biscarrat[1], S. Vitry[1]
[1]CEA Cadarache, Saint Paul lez Durance, France
[2]University of Latvia, Riga, Latvia
[3]Grenoble Institute of Technology, Grenoble, France

In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical ... En savoir plus

Numerical Modeling and Performance Optimization Study of a Dehumidification Process in Nuclear Waste Storage

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

One of the main parameters to consider during the nuclear waste storage design phase is the drum corrosion risk. The humid-air corrosion models available in literature predict that, for carbon steel, the phenomena start to become appreciable for relative humidity (RH) values close to ... En savoir plus

Low Reynolds Number Flow Around a Flying Saucer Micro Air Vehicle

S. Cortés[1], D. Güemes[1], R. Ávila[1]
[1]Universidad Nacional Autónoma de México, Mexico City, Mexico

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... En savoir plus

Simulation of Heat Transfer on Periodic Microstructured Surfaces for Evaporation Cooling

M. Hackert-Oschätzchen[1], R. Paul[1], M. Penzel[1], M. Zinecker[1], A. Schubert[1]
[1]Professorship Micromanufacturing Technology, Technische Universität Chemnitz, Chemnitz, Germany

Evaporative cooling is a promising cooling method for dissipating high heat fluxes in high power density applications. One possibility to enhance heat flux is a generation of microstructures into the cooler surface. This enlarges the cooler surface and systematically affects the fluid ... En savoir plus
