In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program architecture is explained and is used to simulate two applications. The first calculates the voltage induced by an ...

With offshore oil and gas exploration and production moving into ever deeper waters, the suspended length of marine risers (transporting hydrocarbons from the seabed to the surface) can easily exceed 3000 meters. One of the major design requirements for risers in (ultra) deep water is to limit the fatigue damage caused by vortex induced vibrations (VIV). Even moderate currents can induce vortex ...

The rheological behaviour of a biphasic material is quite difficult to model because of the difficulties to represent the evolution of the space position of each solid particle in the solid matrix. The first part of this study consider an equivalent material by homogeneisation method. The main point of this first part was the representation of the rotation of the rheological mobile. The second ...

Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in different configurations and operation conditions. Depending on the off/on switched fans, we obtain various air ...

In this work, a COMSOL model that predicts velocity and concentration fields inside an X-shaped millichannel (4 mm diameter) is developed. Water and a ink low concentration are injected simultaneously in the two inlets of the device. The mass transfer problem is solved by a Fickian model (solute concentration is low compared with the solvent). The parameters in this study are: initial inlet mass ...

We aim to develop an in vitro culture system to mimic the human bone marrow stem cell niche in an artificial perfusion bioreactor environment to culture human adult stem cells. State of the art human bone marrow stem cell research shows that even smallest changes in the physical, thermo dynamical or biochemical environment induce a differentiation of human bone marrow stem cells into other cell ...

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of humidity from the support. The general objective of this study is the understanding of the blistering phenomenon. ...

This paper gives an overview of modelling microsensors on geometry and system level. The focus will be on the generation of the multiphysics reduced order system model and the coupling with package and ASIC models. The method is based on modal superposition. This means all the details of the sensor can be considered in a finite element model. The mechanical mode shapes of this model form the ...

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

Various haematological diseases, including leukaemia, are characterized by abnormal production of particular blood cells. Two important properties of haematopoietic stem cells (HSCs) are used in their therapy, namely: a) rapid migratory activity and ability to \'\'home\'\' to their niche in the bone marrow; b) high self-renewal and differentiation capacity, responsible for the production and ...
