This paper presents a numerical model based on the mild-slope equation (MSE for short) solved using the PDE mode of the software COMSOL Multiphysics suitable to reproduce the propagation of small amplitude tsunamis in the off-shore field. The model solves the governing equations in the ... Mehr lesen
To understand a metal susceptibility to Hydrogen Embrittlement (HE), it is important to quantify the diffusion of hydrogen through a metallic membrane. Electrochemical permeation tests are the most common methods for experimentally determining the diffusion coefficient of a metal. ... Mehr lesen
The presented paper describes a method for micro precision assembly of very small objects like future microchips, which have a lateral expansion equal to or smaller than 500 μm. The modelling and simulation of a fluidicbased micro assembly method for a microchip with a dimension of ... Mehr lesen
We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that ...

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 ... Mehr lesen
This paper presents a finite element method based modeling and design of control for distributed parameter systems. First, models of distributed parameter systems in the form of lumped-input/distributed-output systems and structure of control loop are introduced. Next, modeling of ... Mehr lesen
The mixer-settler principle is commonly used for industrial extraction processes. This is done by mixing the two immiscible liquids to perform mass transfer and subsequently separating them in gravity settler. However, when drop size becomes small, separation in a settler becomes ... Mehr lesen
We present a full modal -analysis of optical and acoustic properties based on two-dimensional finite-element method (2D-FEM) for Brillouin Gain spectrum (BGS) determination in optical fibers with COMSOL. This model enables us to predict precisely the BGS of any kind of silica fiber ... Mehr lesen
The aim of this work is to present a simple multiphysics simulation using COMSOL able to describe combustion of kerosene vapours in a closed vessel. The emphasis is on the mechanical effects of the reactive processes. The evolution of the thermodynamical variables (pressure, temperature, ... Mehr lesen
Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating characteristics. An emerging field is the study of acoustical properties of multi-scale porous materials. An example of these is a double-porosity granular material ... Mehr lesen
