Numerical homogenization is based on the use of finite elements for the description of average properties of materials with heterogeneous microstructure and composites. The Representative Volume Element (RVE) of a masonry is solved with COMSOL Multiphysics®. It consists of linearly ... En savoir plus
This study presents a rotordynamic analysis of a rotor on hydrodynamic bearings using COMSOL Multiphysics®. In this paper, the complexity of the model is gradually increased. Starting point of the analysis is the modal analysis of the rotor in free-free conditions. A Reynolds model is ... En savoir plus
Polymer Electrolyte Fuel Cells (PEFCs) are a key technology in the advancement of society towards a low carbon future, in particular for use within the automotive sector. PEFCs are advantageous due to their low operating temperature (60-80 deg.C), quick start up times and responsiveness ... En savoir plus
A two-dimensional stationary model of a vanadium oxygen fuel cell is developed in COMSOL Multiphysics®. This energy storage device combines a vanadium flow battery anode and an oxygen fuel cell cathode. The oxygen reduction reaction generates additional water, leading to a degradation of ...

In automotive industry, regardless the type of engine we use, heating and air-conditioning is responsible for the highest energy consumption among all the auxiliary systems all over the year. For conventional vehicles with thermal engines, the heating of the internal space is easy ... En savoir plus
This paper describes the design and characterization of an 8 slots resonant cavity Magnetron, which undergoes thermal-structural effects due to cathode heating. The proposed study involves Thermal Stress, Eigen-frequency and Particle Tracing analysis based on COMSOL Multiphysics®. ... En savoir plus
Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same ... En savoir plus
The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase ... En savoir plus
In the finite element based modeling and simulations only the coherent propagation of light is considered. However, in reality when light passes the thick layer it loses the phase information and its coherent nature due to the spatial, temporal or spectral incoherence. In this work, we ... En savoir plus
A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as ... En savoir plus
