  2. 1. Optimisation of the Flow Process in Engine Bays - 3D Modelling of Cooling Airflow

    Author : Peter Gullberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling Airflow; UTM; Fans; CFD;

    Abstract : The focus of today’s automotive industry is to reduce emissionsand fuel consumption of all vehicles. Concentrating on the truckindustry, the last 20 years have focused largely on cutting emissionsof particulate matter and nitrogen oxides. For the future, attentionwill be on fuel consumption and emissions of carbon dioxide. READ MORE

  4. 2. Computational Fluid Dynamics and Experimental Studies of the Urea-SCR System

    Author : Andreas Lundström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea; SCR; decomposition; CYA; HNCO; NH3; CFD; thermolysis;

    Abstract : Volatile emissions produced by the burning of fossil fuels may be converted on a catalyst to less harmful products. During lean combustion an excess of oxygen in the exhaust gases together with a catalyst effectively oxidizes carbon monoxide and hydrocarbons into carbon dioxide and water. READ MORE

  5. 3. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Author : Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

  6. 4. Combustion Characteristics of a Swirl Dry Low Emission Burner Concept for Gas Turbine Application : Experiments and Simulations

    Author : Atanu Kundu; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas Trubine Combustion; Partially Premixed flame; Flame stabilization; Swirl Flow; Emission; Experiments; Combustor; CFD; PLIF; PIV; Chemiluminescence;

    Abstract : In the current global energy scenario, gas turbine can provide delicate balance between the booming worlds energy requirement and a pollutant free sustainable society. Cleaner combustion of fuel (particular natural gas), efficient, reliable, low maintenance and cost effective operation of gas turbine attracted scientific community to push the limit further (high efficiency and zero emission gas turbine).

  7. 5. Numerical Investigation of Internal Combustion Engine Related Flows

    Author : Martin Söder; Laszlo Fuchs; Martin Tunér; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; LES; Engine; Intake; Compression;

    Abstract : Internal combustion engines has been used for more than 100 years. The use of the abundant energy supply stored as hydrocarbon fueled unprecedented economic growth. The use of hydrocarbons increased the work output of human labor significantly, thus increasing the economy and prosperity. READ MORE
