  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; Lunds universitet.; Lund University.; [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 : Popular Abstract in Swedish I utvecklingen av gasturbiner och förbränningsmotorer (som används i bilar, flygplan & båtar) finns idag ett modernt miljötänkande som strävar efter att reducera utsläpp och öka effektiviteten (verkningsgraden). Med användning av rätt kylmetoder kan man påverka dessa parametrar. 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; Lunds universitet.; Lund University.; [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 : Popular Abstract in Swedish Beräkningar med detaljerade kemiska reaktionssytem, med uppemot 1500 kemiska reaktioner, har utförts på HCCI-motorer, en experimentell motortyp som bygger på homogen kompressionsantändning. Resultaten jämfördes med experimentella mätningar och visade att beräkningar med god noggrannhet kan utföras, men att antändingsprocessen är mycket känslig för även små variationer i temperatur, bränsleblandning, och eventuella felaktigheter i reaktionsmekanismen.

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

    University dissertation from Lund University (Media-Tryck)

    Author : Mehdi Bahador; Lunds universitet.; Lund University.; [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
