  2. 6. Mixing of Large Solids in Fluidized Beds

    Author : Anna Köhler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluidized beds; magnetic particle tracking; drag; semiempirical modelling; fluid-dynamic downscaling;

    Abstract : Fluidization is a technology that is widely used in systems in which particulate solids are to be transported, mixed, and/or reacted with gases. In fluidized bed applications, the lateral mixing rate of the solids and the heat and mass transfer with their surroundings play important roles in process performance. READ MORE

  5. 8. Fuel dispersion and bubble flow distribution in fluidized beds

    Author : Johanna Olsson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidised bed; fuel mixing; bubble distribution; digital image analysis; particle tracking; Energi och material; Resource Recovery; Resursåtervinning;

    Abstract : Fluidized bed technology is used for thermal conversion of solid fuels (combustion and gasification) and is especially suitable for conversion of low-rank fuels such as biomass and waste. The performance of fluidized bed units depends on the fuel mixing and fuel-gas contact. READ MORE

  6. 9. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines

    Author : Simon Reifarth; Hans-Erik Ångström; Nils Tillmark; Andreas Cronhjort; José Galindo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EGR; Exergy; mixing; pulsating flow; HP-EGR; LP-EGR; high-pressure EGR; low-pressure EGR;

    Abstract : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. READ MORE

  7. 10. Investigation of jet pulsation effects on near-nozzle mixing and entrainment

    Author : Alexander Nygård; Laszlo Fuchs; Lisa Prahl Wittberg; Mireia Altimira; Xandra Margot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sprays; Nozzle; Mixing; Pulsation; Engineering Mechanics; Teknisk mekanik;

    Abstract : Turbulent jet flows are very common in engineering applications. One example is that of fuel injection in internal combustion engines, which is closely related to the combustion process. Because of the widespread use, the resulting emissions of such engines have a significant impact on human health and the environment. READ MORE
