  1. 1. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting

    University essay from KTH/Produktionsutveckling

    Author : Marilena Wiele; Murad Abulawi; [2023]
    Keywords : Electron beam melting; Additive manufacturing; Electric motor windings; Hairpin windings; Winding design; Copper; Parameter optimization; Electrical conductivity; Elektronstrålesmältning; Additiv tillverkning; Elmotorlindningar; Hårnålslindningar; Lindningsdesign; Koppar; Parameteroptimering; Elektrisk ledningsförmåga;

    Abstract : Within the framework of this thesis, the electron beam melting of pure copper for the purpose of producing electrical windings was examined. The conventional manufacturing process of copper windings was investigated, and the potential advantages offered by the design freedom inherent in the electron beam melting process were explored.

  3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  4. 3. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

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

    Author : Namika Maharjan; [2023]
    Keywords : Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Abstract : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. READ MORE

  5. 4. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pranay Kumar Parsi; [2023]
    Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

    Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

  6. 5. THE WIND OF CHANGE – SENSITIVITY OF THREE PARAMETERS ON WIND POWER ENERGY CALCULATIONS USING WINDPRO SOFTWARE

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nina Skuja; [2023]
    Keywords : Error; Sensitivity; WindPRO; Wind Power; Wind Speed; Roughness; Power Curve; Energy Production; Wind Resource Assessment;

    Abstract : Many parameters used for Wind Resource Assessment (WRA) have uncertainty and variability, yet are input into the process as single values. The extent of the uncertainty or variance may not be known, and may or may not be significant enough to affect output. READ MORE
