  1. 21. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Hanna Sjöman; [2023]
    Nyckelord :Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

    Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER

  3. 22. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Arjun Monga; [2023]
    Nyckelord :coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

    Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER

  4. 23. Evaluation of The Impact of Automated Driven Vehicles on Traffic Performance at Four-leg Signalized Intersections

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Ahmed Osman; [2023]
    Nyckelord :Automated driven vehicles; Microscopic simulation; PTV VISSIM; Traffic performance; signalized intersection;

    Sammanfattning : Intersections, particularly four-leg signalized intersections, are frequent sites of traffic congestion in urban areas. This congestion can lead to delays, increased travel time, and a negative impact on traffic performance and quality of life for people. LÄS MER

  5. 24. Control Aid Implementation -Modelling and simulation of triple extruder-

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Karl Langsér; [2023]
    Nyckelord :Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

    Sammanfattning : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. LÄS MER

  7. 25. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

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

    Sammanfattning : 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. LÄS MER
