  1. 26. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Madeleine Durdek; [2023]
    Nyckelord :Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Sammanfattning : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. LÄS MER

  3. 27. Investigation of flux dependence on viscosity in ultrafiltration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Peter Bourghardt; [2023]
    Nyckelord :ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Sammanfattning : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. LÄS MER

  4. 28. Användning av riskbegreppet i en dagvattenkontext : En litteraturstudie om hur riskbegrepp används vid dimensionering av ledningsnät för dagvatten

    Kandidat-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnea Knutsson; [2023]
    Nyckelord :risk; stormwater network; climate change; infrastructure capacity design; adaption strategy; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Climate change and urbanization is a threat for existing stormwater networks. Many stormwater networks are designed after historical rain data that will fail to predict future events due to large changes in rainfall patterns caused by climate change and urbanization. LÄS MER

  5. 29. Investigation of coarse-grid CFD approach for nuclear engineering application

    Master-uppsats, KTH/Fysik

    Författare :Michela Casarella; [2023]
    Nyckelord :Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

    Sammanfattning : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

  7. 30. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Johan Humla; Samuel Friman; [2023]
    Nyckelord :;

    Sammanfattning : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. LÄS MER
