  1. 1. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

  2. 2. Investigation of Governing Physics in a PEM Electrolyzer

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kian Hajireza; [2020]
    Nyckelord :electrochemistry; polymer-electrolyte membrane; electrolysis; hydrogen production; COMSOL; physics-based mode; multiphase transport; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Hydrogen gas is an energy source that has an energy density (per mass) that is three times as large than the energy density of natural gas. This qualifies hydrogen gas as a prime candidate for the fuel of tomorrow. One of the main research areas for hydrogen include the production of it as there are a vast amount of methods of hydrogen production. LÄS MER

  3. 3. Raman Spectroscopy for Characterizing Porous carbon

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Rima Zuriah Amdani; [2020]
    Nyckelord :Raman Spectroscopy; Porous Carbon; Biochar; Carbonization; Aromaticity; Physics and Astronomy; Technology and Engineering; Chemistry;

    Sammanfattning : Porous carbon obtained from low cost and abundant biomass has gained attention as renewable material feedstock. In this study, porous carbon biochar produced through pyrolysis was investigated by Raman spectroscopy to disclose the structural properties. LÄS MER

  4. 4. Entanglement in a quantum heat engine

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Harald Öhrn; [2020]
    Nyckelord :Quantum physics; Entanglement; Quantum heat engine; Physics and Astronomy;

    Sammanfattning : In 2015 Jonatan Bohr Brask et al. showed that steady-state entanglement could be generated in two interacting qubits incoherently coupled to thermal baths of different temperatures [1]. LÄS MER

  5. 5. DEVELOPMENT OF RISK INFORMED METHODS FOR ESTIMATING RADIATION RELEASE FROM CABLE FIRES AT HIGH ENERGY PHYSICS FACILITIES

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Funk; [2020]
    Nyckelord :Fire Safety Engineering; CERN; Fire-induced Radiological release; particle accelerator; Fire Protection; Fire Risk Analysis; Technology and Engineering;

    Sammanfattning : CERN operates the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. The LHC was built to advance the state of knowledge in particle physics by increasing the energy of colliding particles to the TeV range. LÄS MER
