The model for study of thermal mechanical behavior of multilayer thin films was developed. The stress-strain analysis was carried out in combination with thermal effects. The 2D thinfilm model has been solved by FEMLAB 3.1i. The middle layer was thermally loaded with Ohmic heating and other layer’s thicknesses were varied in time. All material data like elastic coefficients, thermal ...

The BioMEMS (Bio-Electro-Mechanical Systems) have become of considerable interest because they constitute a converging solution for many pluridisciplinary studies. The different covered fields are the biology (single cell, proteins, enzymes, neurons…), the chemistry (polymers), microelectronics and the microtechnologies associated with. Devices whose aim is the study of biological entities are ...
Evaluation of electric impedance spectra for single bio-cells in microfluidic devices using combined FEMLAB/ELDO modeling
Senez, V., Arscott, S.
This paper describes a simple method to predict the electrical impedance spectrum of single and cultured cells in micro-devices. It can be used for the rapid design of micro-sensors as well as for more fundamental studies about the interactions of electric fields with bio-cells. The finite element (FEMLAB) and the transport lattice (ELDO) methods are coupled through the MATLAB environment for ...

The self-induced ion plating (SIIP) process is a new physical vapor deposition process based on the evaporation of a metallic target (i.e. tin) thanks to a magnetron sputtering system. The aim of this work is to develop a numerical simulation model of the SIIP process in order to predict the target temperature field and from it, the coating profile on the substrate. The simulation of the SIIP ...

We use GPS measurements and Finite Element analysis to investigate strain accumulation in the interaction between active fronts of the Southern Alps and Dinarides at the northern edge of the Adriatic micro-plate. We develop a three dimensional model of the area taking into account the regional topography, approximating the crust as an elasto-plastic medium and reproducing as close as possible the ...

A discharge of hydraulic oil is assumed from an hydroelectric power station. The oil is let out through the outlet from the turbines and is spread into the river. The flow of water, or more correctly, the solution of water and oil, is calculated by Navier-Stoke equation for incompressible fluids. The concentration of oil is calculated by a mass-balance equation. It is assumed that oil is absorbed ...

The method to derive upscaled expressions for the dispersion coefficients for reactive flow in a porous medium uses a periodic unit cell (PUC), which consists for instance of a spherical grain in a cube, but nothing prohibits defining more complex PUC's. Homogenization leads to a coupled system of equations where the flow is described by Stokes equation and the concentration fluctuation is ...

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.
