  1. 1. Kvillebäcken : analys och gestaltningsförslag - me[d]andra strukturer och processer

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Louise Stigsson Rigné; Emil Vernersson; [2024]
    Keywords : Urbanekologi; landskapsarkitektur; hydrologi; vattendrag; naturbaserade lösningar; blågrön infrastruktur;

    Abstract : I byggandet av hållbara städer är utveckling av blågrön infrastruktur högaktuell, och inom detta faller stort fokus på utveckling av urbana vattendrags ekologi, vattenkvalitet, och förmåga att omhänderta konsekvenser av klimatförändringar. Få vattendrag uppnår miljökvalitetsnormerna, och platsspecifika utmaningar finns i varje vattendrag. READ MORE

  3. 2. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nadja Rabizadeh; [2023]
    Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

  4. 3. Forced response numerical investigation of a transonic compressor rotor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  5. 4. Analysis of granulated carbide powder and how it affects pressing

    University essay from KTH/Materialvetenskap

    Author : Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Keywords : Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Abstract : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. READ MORE

  6. 5. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE
