  1. 1. Theoretical and Experimental Studies of the Formation of Ionized Gases in Spark Ignition Engines

    University dissertation from Lund Institute of Technology

    Author : Raymond Reinmann; Lund University.; Lunds universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermal Ionization; Calorimetry; Interferometry; Spark Ignition Engine; Current and Voltage Measurements; Engine Control.; fluid dynamics; Gases; plasmas; Gaser; plasma; fluiddynamik; Breakdown; Arc; Glow; Flame Ionization; Chemi-Ionization; Spark; Townsend; Fysicumarkivet A:1998:Reinmann;

    Abstract : The processes that govern the formation, existence and consumption of ions in gases have been studied both experimentally and theoretically. The aim of the work is targeted at increasing the understanding of these phenomena in the working gases inside an engine. READ MORE

  2. 2. Non-CO2 greenhouse gases, uncertainty and land-use competition

    University dissertation from Lund Institute of Technology

    Author : Daniel Johansson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kyoto protocol; energy system; integrated assessment; environmental economics; land use change; bioenergy; climate change; greenhouse gases; GWP;

    Abstract : Over the past 250 years the concentrations of greenhouse gases in the atmosphere have increased drastically. It is close to scientific consensus that these changes have increased the temperature of the earth. READ MORE

  4. 4. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces

    University dissertation from Lund University (Media-Tryck)

    Author : Mehdi Bahador; Lund University.; Lunds universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Termisk teknik; plasmas; Gaser; Thermal Radiation; Scattering; Heat load; Gases; fluid dynamics; Biomass Furnaces; framdrivningssystem; Motorer; Motors and propulsion systems;

    Abstract : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. READ MORE

  5. 5. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors

    University dissertation from Mrs Gunvi Andersson, Div. Heat Transfer, Box 118, 22100 Lund, Sweden

    Author : Andreas Abdon; Lund University.; Lunds universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; plasma; combustor; gas turbine; cooling; numerical simulations; turbulence; ribs; impingement; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. READ MORE
