  1. 1. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

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

    Author : Hyacinthe Ménard; [2024]
    Keywords : District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

    Abstract : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

  3. 2. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mathieu Marmier; [2023]
    Keywords : CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Abstract : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. READ MORE

  4. 3. Linear optimization of a potential microgrid to supply TSK70

    University essay from KTH/Kemi

    Author : Roy Satis; [2023]
    Keywords : modelling; solar power; energy storage; electric vehicle; construction site; modelering; solkraft; energilagring; elektrifierad fordon; konstruktionsplats;

    Abstract : Transport- och byggindustrin är en bidragande orsak till klimatkläget på grund av den betydande mängd växthusgaser som produceras. Att byta till elfordon är en metod för att minska de skadliga effekterna av klimatförändringarna. READ MORE

  5. 4. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zhenyu Li; [2023]
    Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

  6. 5. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
