  1. 1. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application

    Författare :Chen Huang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSB2; Reitz-KHRT; gasoline surrogate; LISA; sensitivity study.; Reitz-Diwakar; Trajectory collision; laminar flame speed; chemical kinetics; TAB; Rosin-Rammler; ignition delay; OpenFOAM; ethanol; O Rourke collision; SMD; hollow cone spray; liquid penetration;

    Sammanfattning : The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is direct gasoline injection, which is considered to be an important and cost-effective measure to meet both targets. LÄS MER

  3. 2. Producer Gas Implementation in Steel Reheating Furnaces from Lab to Industrial Scale : A Computational Fluid Dynamics and Thermodynamics Approach

    Författare :Mohsen Saffari Pour; Pär Göran Jönsson; Henrik Saxen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The integrated steel-making plants in Sweden contributed with approximately 8 % of the total CO2 emissions in the country in 2011. A major contributor to these emissions is the combustion of fossil fuels in different process units. Therefore, it is essential to reduce emissions by limiting the fossil fuels consumption in the steel industry. LÄS MER

  4. 3. Penetrablity for cementitious injection groups

    Författare :Daniel Eklund; KTH; []
    Nyckelord :;

    Sammanfattning : Grouting as a method of strengthening and sealing rock, soiland concrete is widely spread. The possibilities of sealingstructures are of great importance in both economical andenvironmental point of view. The costs of grouting have incertain projects been as high as the cost for the blasting andexcavation of the tunnel. LÄS MER

  5. 4. Large-eddy simulation on the effects of fuel injection pressure on gasoline spray characteristics

    Författare :Sandip Wadekar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High pressure fuel-injection; GDI engine; LES; Spray characteristics;

    Sammanfattning : Increasing the injection pressure in gasoline direct injection engines has a substantial potential to reduce emissions while maintaining high efficiency in spark ignition engines. Present gasoline injectors operate at pressures of 20 to 30 MPa. LÄS MER
