In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a carrier fluid (buffer), are introduced into a reaction channel via a Y-shaped double-inlet. As the streams flow ...

High intensity discharge lamps can experience flickering and even destruction, when operated at high frequency alternating current. The cause of these problems has been identified as acoustic resonances inside the lamp’s are tube. Here, a finite element approach for the calculation of the acoustic response function is described. The developed model does not include the plasma dynamics.

The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors contribute to ET dysfunction in certain patients. We model the ET in COMSOL using geometric data obtained ...

Heat and mass transfer involved in drying is studied by using COMSOL 3.4. The effect of air temperature on the performance of the drying process applied to fresh food slices is scrutinized. COMSOL’s flexible formulation is exploited by using special drying kinetics for the substrate, and by including a treatment of the dependence of the properties upon the residual moisture content. The model ...

Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time frames involved. Performing a safety analysis of a radioactive waste disposal system requires therefore ...

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...

RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For validation purposes, results from RFSP-IST are often compared with those from other codes. This paper documents the ...

In an earlier work we developed a finite element bidomain model of an aplysia abdominal ganglion in order to estimate the sensitivity of this contrast mechanism to changes in cell membrane conductance occurring during a gill-withdrawal reflex. We used our model to determine both current density and magnetic potential distributions within a sample chamber containing an isolated ganglion when it ...

Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic system for living cell culture and assay. The system can be used as a generic platform to study the behavior of ...
