One big challenge for the food industry is to predict and optimize flavors. The Maillard reaction occurs in food matrices containing carbohydrates and proteins under specific operating conditions. The presented research couples thermal and kinetic modeling to the bread baking process, ... En savoir plus
Reformer and catalytic burners are common components in fuel cell systems, crucial for efficient preparation of fuel and exhaust gases of the fuel cell stack. We intend to show the influence of radiation to the temperature distribution inside of a reformer unit. The model consists of an ... En savoir plus
The 3D unit cell model approach offers an efficient tool to analyze the influences of geometrical design (channel shape and arrangement, filter length, wall thickness) and filter material properties (permeability, soot loading characteristics) on the performance of ceramic particle ...

Heap leaching in the mining industry had become a sophisticated practice at least 500 years ago. It is a mineral processing technology whereby piles of crushed Run-of–Mine rock are leached with chemical solutions to extract minerals. The goal of this work is to contribute to the ... En savoir plus
Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of ... En savoir plus
Olkiluoto at Eurajoki has been selected as the final repository site for spent nuclear waste in Finland. This area has been affected, at regional scale, by land-uplift processes related to the ice withdrawal. These events have resulted in a complex and stratified heterogeneous ... En savoir plus
UCG is a process which converts coal to syn gas at the underground coal seam itself. UCG can help meeting the rising energy demand by utilizing coal resources that otherwise would be too deep, or of poor quality, or simply not economical to mine. As UCG takes place, a cavity is formed ... En savoir plus
After rapid mixing of waste water and coagulant, an effective slow mixing during a reasonable retention time will cause to grow the size of flocs up which will settle out easily. Around-the-end hydraulic mixer with barriers is one of the efficient facilities that have been used in water ... 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 ...
