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 ...

In the paper will be presented the construction of passive magnetic suspension with superconductors. The system of magnetic suspension was designed for GBRIEL project. There is presented numerical test bench of passive magnetic suspension with superconductor. This kind of suspension was ... En savoir plus
In ESA's Cosmic Vision program, the Japanese SPICA satellite is a mission of opportunity in the M-class, with the SAFARI instrument being one of the next generation space-borne astronomy instruments being developed to take advantage of SPICA’s cryogenically cooled 3-m class primary ...
