We deal with a problem of bentonite behavior during the saturation process in a high level waste repository of KBS-3V conception, SKB (2010). Bentonite is a type of clay with specific nonlinear behavior caused by water adsorption and swelling ability in contact with water. We solve ... En savoir plus
The influences of curvature effects and swirl intensities for Non-Newtonian viscous fluid flow in a curved tube have been numerically investigated by using COMSOL Multiphysics®. The twisted tape, which are located directly in front of the curved part, are used as swirl flow generators. ... En savoir plus
Woven composites with basalt reinforcement plain 1x1 are examined to define structural mechanics. Woven composites were created by the prepreg technology, 8 layers of plain-weave basalt fabrics were saturated by the precursor, polysiloxane matrix Lukosil®, and joint pressed during ...

Most models of biological pattern formation are simulated on continuous domains even though cells are discrete objects that provide internal boundaries to the diffusion of regulatory components. In our previous papers on simulating organogenesis in COMSOL Multiphysics® (Germann et al ... En savoir plus
Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our ... En savoir plus
With a view to estimating electrical characteristics of a Polymer Li-ion Battery during specific charge and discharge conditions, a COMSOL Multiphysics® model has been developed that accounts for electrochemical phenomena inside the device. Cell model has been created using the Li-Ion ... En savoir plus
The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT ... En savoir plus
Within this study a model of a single discharge of micro scale EDM was developed in accordance with Schulze et al [1]. The specific computation of the growth of the plasma channel has been derived from this literature. Applying COMSOL Multiphysics® a pseudo 3-D geometry was created based ... En savoir plus
Evaporative cooling is a promising cooling method for dissipating high heat fluxes in high power density applications. One possibility to enhance heat flux is a generation of microstructures into the cooler surface. This enlarges the cooler surface and systematically affects the fluid ... En savoir plus
A grand variety of microactuator technologies and demonstrators has been introduced during the last years. Of particular interest are the microactuators based on phase change materials and especially paraffin wax, which can volumetrically expand up to 15%, providing high force actuation. ... En savoir plus
