  1. 1. Prospects for Wind Energy Development in Consideration of a Cumulative Appraisal of Botanical, Faunal, Societal, and Cultural Values in Swedish Boreal Forests

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Robin Alexander Gallus; [2023]
    Keywords : Wind Energy; Boreal; Forest; Sweden; Cumulative; Weighted Overlay Analysis; Woodland Key Habitat;

    Abstract : Renewable energy development is breaking global records each year. European and national Swedish legislation target substantial portions of wind energy production by 2040. Sweden has ambitious objectives for wind energy, with plans to nearly triple its wind energy proportion in the next 17 years. READ MORE

  3. 2. ORC systems for small scale energy production : Improving the prediction of electricity production of ORC turbines under varying loads

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Kristina Pettersson; [2021]
    Keywords : ;

    Abstract : In order to have a sustainable, resource-efficient energy system and no net emissions of greenhouse gases by 2050, energy efficiency is one important aspect to reach this goal and develop a long-term sustainable energy system. As part of a solution to increase energy efficiency in society, Organic Rankine Cycle (ORC) systems can have a far reaching effect by utilizing low-grade heat to produce electricity. READ MORE

  4. 3. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE

  5. 4. Creating a Dynamic Model of a Gas Turbine in the MVEM Framework Using an Ellipse Compressor Model

    University essay from Linköpings universitet/Fordonssystem

    Author : Edvin Hansson; [2020]
    Keywords : Gas turbine; Modeling; control;

    Abstract : The legislations on greenhouse gas emissions are getting tougher and tougher every year. This drives the demand for energy efficient gas turbines with as low emissions as possible. This poses the challenge to manufacturers of constructing gas turbines with lessened environmental impact, but with maintained performance. READ MORE

  6. 5. LCA of Microgrid System: a Case Study at ‘North-five Islands’ of Changshan Archipelago, China

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

    Author : Jiang Yuning; [2019]
    Keywords : Microgrid system; Life cycle Assessment LCA ; Climate change impact; Greenhouse gas emissions GHG ; China;

    Abstract : Microgrid can provide stable, clean, and sustainable electricity supply for remote places since it can operate on renewable energy sources and work isolated from the utility grid. This thesis evaluates the life cycle greenhouse gas (GHG) emissions of the microgrid system which is located at the ‘North-five Islands’ of Changshan archipelago in China. READ MORE
