  1. 21. Fluid Surface Velocity Measurement Using Millimeter-Wave Radar Sensor

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Gustav Broman; Leo Ghatnekar Nilsson; [2022]
    Nyckelord :Fluid flow surface measurement; velocity estimation; FFT; fast-time phase change; radar.; Mathematics and Statistics;

    Sammanfattning : Contactless fluid surface velocity measurements with radar technology presents novel ways of determining fluid flow. The Acconeer A121 sensor is used, which is a pulsed coherent 60 GHz millimeter-wave radar, with high accuracy and low energy consumption. LÄS MER

  3. 22. 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

  4. 23. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
    Nyckelord :HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

    Sammanfattning : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

  5. 24. En Jämförelse Mellan Rheogjutning Och Konventionell Pressgjutning Med Vakuum. : Vid Tillverkning Av Aluminiumkomponenter.

    M1-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Marisa Ling Brännlund; Hanna Martinsson; [2021]
    Nyckelord :semi-solid; rheocasting; rheogjutning; pressgjutning med vakuum; gjutning; RheoMetal;

    Sammanfattning : The car industry is constantly under pressure to be competitive in their product development which includes not only safety and increased performance, but also in their environmental impact. Volvo Cars strives to be more environmental and high performing in their product development, which of course includes manufacturing methods since these highly effect a components environmental impact and mechanical performance.

  7. 25. Modelling of water and material transport in River Storån to Lake Bolmen

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Imjal Sukupayo; [2021]
    Nyckelord :Brownification; Water Color; Dissolved Organic Matter; Discharge; hydraulic analysis; Tracer Analysis; Dispersion coefficient; Advection and Diffusion; Bolmen Lake; Storån River; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. LÄS MER
