  1. 21. The impact from varying wind parameters and climate zones on building energy use : A case study on two multi-family buildings in Sweden using building energy simulation

    University essay from Linköpings universitet/Energisystem

    Author : Karthickraj Tamilvanan; Sai Kiran Mathipadi; [2020]
    Keywords : Building energy simulation; Building energy use; IDA-ICE; Wind effects; wind speed;

    Abstract : Globally, buildings utilize 35 % of the final energy use and contribute to approximately one-third of CO2 emissions. Hence, reducing the energy use of buildings contributes to a large amount of CO2 emissions to be decreased. READ MORE

  3. 22. A simplified vortex method for wind turbine simulation

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Sandro Malusa; [2019]
    Keywords : Wind turbine; Vortex model; Numerical wake model; Vortex sheet; Vortex filament; Tjaereborg; Biot-Savart law; Iterative method;

    Abstract : A new vortex model for wind turbines was developed in order to evaluate the loads at the blades and other important characteristics of interest for the wind industry such as power and thrust coefficients. Nowadays, the calculation of these quantaties is done in a reliable and precise manner with LES simulation using actuator line or actuator disk models. READ MORE

  4. 23. Vad kommer 1 % höjning av krontäckningsgraden få för effekt för Möllevångens lokalklimat? : en analys av projektet Grönare Möllan med fokus på ekosystemtjänsten temperaturreglering

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Clara Zetterlund; [2019]
    Keywords : urban värmeö; yttemperatur; strålningstemperatur; trädkrontäckning; temperaturreglering;

    Abstract : Uppsatsen innefattar en vetenskaplig analys av den faktiska effekten av att höja trädkrontäckningsgraden i en urban miljö i Malmö mätt i ekosystemtjänsten temperaturreglering. Bakgrunden är projektet Grönare Möllan som drivs av Malmö stad och omfattar en plantering av 163 nya träd inom området Möllevången som är 53 hektar stort, vilket enligt kommunens egna beräkningar kommer höja krontäckningsgraden med 1 %.

  5. 24. Conjunctive Operation of Hydro and Solar PV Power with Pumped Storage at Kafue Gorge Power Station (Zambia)

    University essay from Högskolan Dalarna/Energiteknik

    Author : Elvis Nyirenda; [2019]
    Keywords : Photovoltaic; Hydro; Power; Storage; Pumped Hydro Storage; Zambia;

    Abstract : This report covers the work carried out to redesign the two existing conventional hydro power stations in Zambia on the Kafue river into the pumped storage facility with solar photovoltaic power so that security of supply and water conservation is achieved to reduce the power deficits during the dry and drought periods. The two stations are Kafue gorge upper power station (KGUPS) and Kafue gorge lower power station (KGLPS) with an installed capacity of 990 MW and 750 MW respectively. READ MORE

  6. 25. Propane Heat Pump Modelling and Monitoring for System Control Analysis

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Fernando Mengod Bautista; [2019]
    Keywords : ;

    Abstract : The objective of this master thesis was the performance analysis of a non-conventional heating system layout based on a propane heat pump unit. The objective had been pursued by monitoring and modelling the system. First, the project focused on monitoring the system, since for a correct modelling it was necessary to have all the data of the system. READ MORE
