Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...

The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on hardware and computer time. Although many problems could be solved by fluid models, results obtained by these ...

Porous membranes with pore sizes in the micrometer scale are required in many micro systems dedicated to biological and chemical applications. If their thickness is in the same dimension like the pore diameter they are called microsieves. On the one hand, a thin membrane guarantees a small flow resistance but on the other hand the mechanical strength is reduced. We developed a process which ...
Dr. Franck Pigeonneau is currently working in the joint laboratory between the Centre National de la Recherche Scientifique (CNRS) and the company Saint-Gobain. He received his Ph. D. in 1998 from the University Pierre et Marie Curie (Paris, France). His main research activities are devoted to the transport phenomena in high viscous fluids relevant for glass melting processes. He is using COMSOL ...

This work deals with the computer simulation of the blood flow, the arterial wall deformation and their 3D bidirectional interaction, including initial stresses and root displacements. The flow is laminar and steady with flexible walls modeled with a hyperelastic Demiray material model. Poiseuille formula is used to check the bidirectional interaction. 2D axisymmetric and full 3D models have ...

In this paper we introduce a elastic and hyperelastic model to describe the pressure dependent material stress in joint cartilage. We used the pressure dependent E-modulus E = f(s) to calculate the material stress. E = f(s) is a degree 4 polynomial . The indentor was pressed 0.4 mm into the tissue. The results show that the maximal stress at the contact zone between indentor and cartilage ...

The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at NILPRP – Magurele, Romania. The developed system for thin film deposition using thermionic vacuum arc (TVA) ...

We deal with Liquid Crystal Elastomers (LCEs) having hybrid alignment (HNEs), that is, fabricated with a given non-homogeneous nematic orientation. For such a materials, permanent distortions induced by deswelling can be compensated by those resulting from cooling below the transition temperature, thus yielding the possibility of producing temperature-driven actuators. Here, we simulate the ...
