  2. 1. Computer Modeling of HCCI Combustion

    Author : Roy Ogink; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; detailed-chemistry; surrogate fuel; homogeneous charge compression ignition; internal combustion engines; modeling; HCCI; gasoline; auto-ignition; combustion;

    Abstract : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. READ MORE

  4. 2. Biodiesel Spray Combustion Modeling Based on a Detailed Chemistry Approach

    Author : Junfeng Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduction and Validation; Spray Characteristics; Detailed Chemistry; Biodiesel;

    Abstract : Replacing conventional diesel fuels with biodiesel has the potential to drastically reduce engine-out emissions of soot, carbon monoxide, and total unburnt hydrocarbons, at the cost of slightly increased nitrogen oxide emissions. However, to realize the full benefits of using biofuels in this way, there is a need for theoretical models describing their combustion in internal combustion engines. READ MORE

    Abstract : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. READ MORE

  6. 4. CFD Modeling of Combustion in Flexi-Fuel Burners at Gas Turbine Conditions

    Author : Abdallah Abou-Taouk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAS-SST; Global reaction mechanism; CFD; LES; RANS; Combustion; PSR; Chemistry;

    Abstract : The main source of energy in the nearest future will come from fossil fuels. Increasing demands on environmentally friendly energy conversion implies that pollutants, such as CO and NOx, need to be reduced. READ MORE

  7. 5. Bio-diesel Spray Combustion Modeling Based on a Detailed Chemistry Approach

    Author : Junfeng Yang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine modeling; bio-diesel; thermo-physical properties; detailed chemistry combustion; emissions formation; spray characteristics;

    Abstract : The increased use of bio-diesel fuel is expected to reduce emissions of carbon-containing greenhouse gases. To optimize the application of bio-diesel in internal combustion engines, a theoretical model has been developed. READ MORE
