  1. 1. Thermal and flow field validation of lattice Boltzmann method solver

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : André Skagius-Kallin; [2023]
    Keywords : Lattice Boltzmann method; heat transfer; flow field;

    Abstract : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. READ MORE

  3. 2. Taking Flight Towards a Greener Future: Steps Airlines Can Take to Reduce Emissions

    University essay from Lunds universitet/Trafikflyghögskolan

    Author : Rabin Kronold; Mikael Nyström; [2023]
    Keywords : Sustainability; Aviation; Management; Emissions; Carbon footprint; Ground and aircraft operation; Fuel consumption; Contrails; Aircraft-Induced Clouds; Greenhouse gas emissions; Sustainable Aviation Fuel; FLYL01; Technology and Engineering;

    Abstract : Background: For decades, aviation has been an important part of society and with its growth comes the increased environmental impact and the challenge to reduce this adversary effect and move towards sustainability.

  4. 3. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  5. 4. Studying Elliptic Flow in High Centrality Pb-Pb Collisions using Proton Collision Background Fitting

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Philip Fredholm; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In this report, the elliptic flow in high centrality Pb-Pb collisions is calculated using two particle correlations $v_2\{2\}$ but without any imposed separation in η with data taken from the ALICE experiment at CERN in 2015. Instead, measurements of the same correlations in proton-proton collisions is used as a background to account for non-flow effects and data is correlated between the time projection chamber and the forward multiplicity detectors in order to avoid intra-jet correlations.

  6. 5. Improving jet printing quality for printed circuit boards : Optimizing first dot jetting deposition through experimental design and response surface methodology

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : William Hedlund; Gustav Sjöberg; [2023]
    Keywords : PCB; printed circuit board; piezo-actuation profile; quality; My700; solder paste; jet printer; jet printing; experimental design; experimental approach; waveform;

    Abstract : Printed circuit boards (PCBs) are essential components in various electronic devices, playing a vital role in their functionality. Over time, PCBs have evolved significantly, becoming smaller, more complex, and multi-layered to meet the demands of advancing technology and consumer preferences. READ MORE
