  1. 1. 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

  2. 2. Homogeneous Ignition - Chemical Kinetic Studies for IC-Engine Applications

    University dissertation from Combustion Physics, Lund Institute of Technology

    Author : Per Amnéus; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Skeletal mechanism; Mechanism reduction; n-heptane; iso-octane; formaldehyde; methane; Motors and propulsion systems; Motorer; framdrivningssystem; Physics; Fysik; Detailed chemistry; Kinetic calculations; Engine knock; Homogeneous charge compression ignition; HCCI; Fysicumarkivet A:2002:Amnéus;

    Abstract : Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. READ MORE

  5. 5. 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
