  1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Charlotte Sophie Gausa; [2024]
    Nyckelord :Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

    Sammanfattning : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

  3. 2. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Bromwel Apondi; [2023-08-17]
    Nyckelord :Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

    Sammanfattning : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. LÄS MER

  4. 3. Optimering av flyghastighet för flygplan

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Louise Larsson; [2023]
    Nyckelord :Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

    Sammanfattning : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. LÄS MER

  5. 4. Framtagning av testrigg för att testa regnerosion på vindturbinblad

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

    Författare :Nils Arvidsson Lindbäck; David Johansson; [2023]
    Nyckelord :leading edge erosion; test rig; wind turbine blades; wind power; kanterosion; testrigg; turbinblad; vindkraftverk;

    Sammanfattning : Bakgrunden till projektet är problem med kanterosion av turbinblad inom vindkraftverks- industrin. Det är ett fenomen som uppstår när turbinblad roterar i höga hastigheter och träffar partiklar, främst vattendroppar i regn. LÄS MER

  7. 5. Assessing Offshore Wind Power Potential in Fiji : A GIS-based Site Suitability and Feasibility Analysis

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

    Författare :Felix Askenberger; Victor Renefalk; [2023]
    Nyckelord :Fiji; Offshore Wind Power; Graphical Information System; Multi-Criteria Site Suitability Analysis; Fiji; Havsbaserad Vindkraft; Grafiska Information System; Multikriterie platslämplighetsanalys;

    Sammanfattning : Renewable energy, including offshore wind power, is expected to play a significant role in mitigating climate change and meeting a growing demand on electricity. Fiji, a Small Island Developing Nation in the South Pacific, needs large quantities of additional renewable energy to achieve its NDC goals and has good natural resources for offshore wind power.
