  1. 1. Development of an Improved Thermal-Hydraulic Modeling of the Jules Horowitz Reactor

    Författare :Reijo Pegonen; Henryk Anglart; Yann Bartosiewicz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jules Horowitz Reactor; CATHARE2; STAR-CCM ; FLICA4; Material Testing Reactor; Computational Fluid Dynamics; System code; Reactor modeling;

    Sammanfattning : The newest European high performance material testing reactor, the Jules Horowitz Reactor, is under construction at CEA Cadarache research center in France. The reactor will support existing and future nuclear reactor technologies, with the first criticality expected at the end of this decade. LÄS MER

  3. 2. Investigation of a Biofilm Reactor Model with Suspended Biomass

    Författare :Alma Masic; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

    Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER

  4. 3. Assessment and improvements of thermal-hydraulic correlations and methods for the analysis of the Jules Horowitz Reactor

    Författare :Alberto Ghione; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Flow instability; Uncertainty; Narrow channels; Jules Horowitz Reactor; Safety analysis; Critical heat flux; Thermal-hydraulic correlations; Heat transfer; Best-Estimate; Material Testing Reactor;

    Sammanfattning : Nuclear research reactors are used to test materials for current and future nuclear technologies, and to produce radioisotopes for medical purposes. Most of the existing Material Testing Reactors in Europe have operated for more than 50 years and new ones are needed. LÄS MER

  5. 4. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling

    Författare :Anna Maria Lindholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx reduction; flow reactor experiments; NOx storage; Pt Ba Al; NSR catalyst; microkinetic modeling; combined NSR and SCR system;

    Sammanfattning : The NOx storage and reduction (NSR) technology is a promising technique to reduce NOx during oxygen excess e.g. in lean burn engine exhaust. A typical NSR catalyst consists of the following components: precious metals, such as platinum, palladium or rhodium, a storage component, usually barium, and a high surface area support, such as γ-alumina.

  7. 5. Miniaturized cell and flow reactor for QCM-D measurements on fluids and soft matter

    Författare :Gabriel Ohlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; soft matter materials; confined volume; Nanocell; QCM-D sensing; miniaturized flow reactor; lipid bilayer; thin films; liquid crystals;

    Sammanfattning : Thin soft matter films are frequently used in many technical applications, where phenomena taking place in the interfacial regions, control film properties and functionality. In order to optimize the latter there is a clear need of methods and tools for probing diverse physical properties of thin soft matter films confined in a nano-sized region. LÄS MER
