  2. 1. High-speed 3D imaging of liquid jets, surfaces and respiratory droplets

    Author : Adrian Roth; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laser Induced Fluorescence; Volumetric imaging; Structured Illumination; 3D Reconstruction; Stereoscopy; 3D Particle Tracking Velocimetry; COVID­19; sprays; respiratory droplets; Fysicumarkivet A:2023:Roth;

    Abstract : Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray­-system in use. READ MORE

  4. 2. LES of Jets and Sprays Injected into Crossflow

    Author : Mirko Salewski; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaser; fluid dynamics; large eddy simulation; spray; plasmas; Gases; lagrangian particle tracking; jet in crossflow; fluiddynamik; plasma;

    Abstract : The objective of this thesis is to numerically simulate a fluid jet injected into a crossflow of the same or another fluid, respectively. Such flows are encountered in many engineering applications in which cooling or mixing plays an important role, e.g. gas turbine combustors. READ MORE

  5. 3. Numerical Studies of Methanol PPC Engines and Diesel Sprays

    Author : Mateusz Pucilowski; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Partially Premixed Combustion PPC ; spray-wall interaction; piston geometry; multiple injections; ICE; ignition front; diffusion flame; combustion mode; RANS; LES; PPC; Diesel spray;

    Abstract : The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). READ MORE

  6. 4. Searches for new physics phenomena with jet final states in the ATLAS detector

    Author : Eva Brottmann Hansen; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle physics; jets; dark matter; Supersymmetry; Hidden Sectors; Fysicumarkivet A:2020:Brottmann;

    Abstract : Collimated sprays of paticle, known as jets,are abundantly produced in high-energy proton-proton (pp) collisions, and are predicted by many theories of physics beyond the Standard Model. This thesis reports first on the calibration of jets with focus on the data-driven in situ calibration. READ MORE
