  1. 26. On the modelling of turbulent flow and mixing in stirred reactors

    Författare :Johan Revstedt; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; CFD; stirred reactors; impeller modelling; Energy research; mixing; LES; Energiforskning;

    Sammanfattning : This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. LÄS MER

  3. 27. Selectivity and sensitivity in supercritical fluid and liquid chromatography, using capillary columns and microelectrochemical detection

    Författare :Susanne R. Wallenborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The obtainable selectivity of capillary column supercritical fluid chromatography wasstudied by the direct and indirect enantiomeric separation of some medium polarcompounds, i.e., benzodiazepines. LÄS MER

  4. 28. Modeling and analysis of heat and mass transfer processes during in-vessel melt progression stage of light water reactor (LWR) severe accidents

    Författare :Robert R. Nourgaliev; KTH; []
    Nyckelord :;

    Sammanfattning : The last two decades of nuclear industry are marked byconsiderable attention tonuclear power plant accidents with core meltdown, knownalsoas severe accidents(SA). Two wellknown severeaccidents, TMI (USA, 1979) and Chernobyl (USSR, 1986), igniteda new wave of publit cancern about safety of existing nuclearpower plants. LÄS MER

  5. 29. Fundamental Aspects on the Re-use of Wood Based Fibres : Porous Structure of Fibres and Ink Detachment

    Författare :Jennie Forsström; Lars Wågberg; Krrister Holmberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : In this work, different aspects on the re-use of wood based fibres have been studied, focusing on ink detachment of flexographic ink from model cellulose surfaces and changes in porous structure of kraft fibres following different treatments. New model systems for evaluation of ink detachment and ink-cellulose interactions were used. LÄS MER
