Interaction of Microparticles in a Miniaturized Vacuum-Cleaner

I. S. M. Jimidar [1], Y. Vanderheyden [1], H. Gardeniers [2], G. Desmet [1],
[1] Vrije Universiteit Brussel, Department of Chemical Engineering, Brussels, Belgium
[2] Universiteit Twente, Mesoscale Chemical Systems MESA+, Enschede, The Netherlands

The ever-growing complexity of samples which need to be processed in e.g., environmental and biomedical/biochemical research, demand higher efficiencies of analytical techniques. Liquid chromatography (LC), mass spectrometry, among others, are analytical techniques that revolutionized ... Mehr lesen

Numerical Calculation of the Three Dimensional Inter-Bar Current Distribution in Induction Machines

J. Güdelhöfer [1], R. Gottkehaskamp [1], A. Möckel [2],
[1] University of Applied Sciences Düsseldorf, Düsseldorf, Germany
[2] Technical University of Ilmenau, Ilmenau, Germany

The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... Mehr lesen

Simulation of Eddy Current Non Destructive Testing using COMSOL Multiphysics®

A. Kyrgiazoglou [1], T. Theodoulidis [1],
[1] Department of Mechanical Engineering, University of Western Macedonia, Kozani, Greece

Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... Mehr lesen

Multiphysical Simulation of an Induction Sealing Process for Cups with Laminated Aluminum Foil

C. Hollenbeck [1], Z. Jildeh [1], P. Kirchner [1], T. Rydlewski [1],
[1] Imagine Engineering GmbH, Bergheim, Germany

The filling process of thermoformed cups with food like yogurt is followed by placing a laminated aluminum foil for hermetic sealing on top of the cup. By today’s standards the sealing of the thermoformed aluminum foil with the cup is primarily realized by contact heat with a hot stamp. ... Mehr lesen

A Novel Free-standing Evanescent Waveguide for Sensing

X. Meng [1], Y. Xin [1], P. French [1],
[1] Department of Microelectronics, Delft University of Technology, Delft, Netherland

Introduction The monitoring of bacteria concentration in drain fluid is the most common way to estimate the success of a colon surgery. However, the lack of efficient method to follow the development of E.coli in drain fluid after surgery is often fatal to the patient. The proposed ... Mehr lesen

Modeling of the Clamping Fixture of a Piezoelectric Cantilever-type Energy Harvesting Device

Over the last decade, ambient vibration energy harvesting by piezoelectric materials has been an area of extensive research. This technology enables to convert wasted mechanical energy available in our environment into useful electrical energy to power up autonomous wireless sensors ... Mehr lesen

Numerical Simulation of PCB-Coil-Layouts for Inductive Energy Transfer Systems

D. Maier [1], N. Lucht [1], A. Enssle [1], A. Lusiewicz [1], J. Fischer [1], U. Pecha[1], N. Parspour [1]
[1] Stuttgart University, Institute of Electrical Energy Conversion, Stuttgart, Germany

This paper presents the two dimensional (2D) Finite Element Method (FEM) COMSOL Multiphysics® model of a PCB-Coil layout. The model comprises of different coil layouts for sake of comparison. The scientific goal of the simulation is to find an optimized arrangement with a high quality ... Mehr lesen

Oxygen Based Diffusion Modeling of Oxidation Behaviour of Encapsulated Lipids

H. Teichmann [1], A. Linke [1], R. Kohlus [1],
[1] Process Engineering and Food Powders, University of Hohenheim, Stuttgart, BW, Germany

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It ... Mehr lesen
