Noninvasive radiofrequency (RF) tissue heating is frequently used for skin tightening and facial wrinkle reduction as alternative to invasive surgical procedures. However, to ensure a safe and efficient therapy, the temperature of the skin and the subcutaneous tissue must be controlled ... En savoir plus
The optimisation of dimensions, materials choice of heaters in annealing furnaces are done with COMSOL Multiphysics® in 2D-axisymetry. Heat losses sources are identified and corrective actions can be taken in function of simulation results. A power saving of more than 50% is achieved ... En savoir plus
Micro-tubular Solid Oxide Fuel Cells (mSOFC) are attracting more and more interest as new generation of energy conversion devices. Although commercial applications still suffer from high costs, there is a need for further improvement of the cell performance, durability and start-up. To ... En savoir plus
Recovery of oil by gas injection is usually inefficient due to the low viscosity of the gas, which results in bypassing of the oil. By adding surfactant solutions it is possible to get in-situ foam formation. Foam has a much higher “viscosity” and hence does not bypass the oil, leading ... En savoir plus
Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... En savoir plus
The electrochemical pickling of steel has two main purposes: 1) To remove thermal oxide; 2) To dissolve chromium-depleted layer, to reinstate the corrosion-resistant properties of the stainless steel; A reliable, flexible and robust 3D model has been made for simulating the steel ... En savoir plus
Today, new processors provide increasing number of cores at rather constant clocking frequency. In sequential optimization algorithms, the forward model simulation is typically accelerated by multiple cores (shared-memory parallelization, SMP), which provides only limited speed-up and ...

The structural design of temporary storage facilities for radioactive waste generally requires the fulfillment of highly severe performance criteria if compared to conventional buildings. This work focuses on the study of the behavior of a steel door subject to the impact of extreme wind ... En savoir plus
Electric resistances are widely used as heating elements in domestic and industrial equipment; since process water contains calcium carbonate and calcium bicarbonate, limescale plays an important role on global efficiency of water-heating systems. Calcium carbonate has a very low thermal ... En savoir plus
This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for ...
