This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... En savoir plus
The construction of high magnetic field superconducting coils requires the use of low temperature superconductors that must be cooled down to liquid helium temperature (4.2 K). Natural two-phase convection loops, i.e. thermosiphon loop, are used as cooling system for large ... En savoir plus
The present project aims at modelling a generator that harvests energy from the variation in blood pressure by exploiting the motion of the arterial wall between the diastolic and systolic phase of the cardiac cycle. The concept is to use a highly electrically conductive fluid, which is ... En savoir plus
This paper proposes a framework for an efficient integration between geometric modeling program and analysis tool for a coming automated aerodynamic design optimization mission. This demand can be addressed by using both in-house codes and commercial software which have the good ability ... En savoir plus
The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... En savoir plus
Silicon solar cells are produced in a series of different process steps in which wet-chemical etching and rinsing steps have a considerable influence on the quality of the wafers. Etching baths are used for surface structuring or intended etch back. Examples therefore are texturing, ... En savoir plus
The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... En savoir plus
Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the ... En savoir plus
A micro Planar Ion Mobility Spectrometer (P-FAIMS) has been simulated using multiphysics software. In P-FAIMS target ions are discriminated by the application of the proper separation voltages to the electrodes of the system. Modelling of vapour phase ions of two compounds have been ...

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation ... En savoir plus
