  1. 1. Studies on Diesel sprays under non-reacting and reacting conditions

    Författare :Chengjun Du; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion flame; OH radical; ethanol; spray vaporization; soot formation; cavitation; turbulent; OH* chemiluminescence; laser extinction; LAS; Diesel sprays;

    Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER

  3. 2. Laser Diagnostics in Reacting Flows

    Författare :Panagiota Stamatoglou; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; planar laser-induced fluorescence PLIF ; gliding arc GA discharge; Plasma Discharges; Turbulence; Combustion Engines; Spectroscopy; high-speed camera HSC ; Burst System; OH-LIF; optical parametric oscillator OPO ; Fysicumarkivet A:2023:Stamatoglou;

    Sammanfattning : Burst-mode laser systems have widely been employed in diagnostics for both reactive and non-reactive flows. Unlike the continuous pulse lasers, burst-mode lasers generate pulses in bursts lasting up to 100 ms, capable to deliver high energies up to Joules per pulse. LÄS MER

  4. 3. Large Eddy Simulation of Swirling Reacting Flows

    Författare :Mohammad Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Swirling flow; Large Eddy Simulation;

    Sammanfattning : The combustion of fossil fuels remains a key technology as these fuels are the main source of energy in the foreseeable future. Heat released in combustion is often accompanied by emission of undesired soot, CO and NOx pollutants. LÄS MER

  5. 4. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows

    Författare :Michael Balthasar; Förbränningsmotorer; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soot; turbulent; flames; engines; turbines; carbon black; ionization; laminar; Physics; Fysik; Fysicumarkivet A:2000:Balthasar;

    Sammanfattning : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. LÄS MER
