  1. 6. Turbine Performance Analysis in Wake and Wake-Free Conditions Using Nacelle Mounted Lidar at a Wind Farm in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Izabela Fijołek; [2022]
    Keywords : Sweden; wind power; onshore; lidar; wake effect; performance analysis; power curve;

    Abstract : The need for optimizing wind farms’ production and maximizing the profitability of projects necessitates power performance analysis. Nowadays, the use of remote sensing devices for this purpose becomes more and more popular due to many advantages this technology has over traditional met masts. READ MORE

  3. 7. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Sara Schützer; [2022]
    Keywords : ;

    Abstract : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). READ MORE

  4. 8. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Fabian Maletzke; [2021]
    Keywords : turbine; blade cooling; matrix cooling; latticework cooling; CFD; heat transfer; RANS;

    Abstract : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. READ MORE

  5. 9. The fate of stars born in gas-rich high redshift galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Floor van Donkelaar; [2021]
    Keywords : Physics and Astronomy;

    Abstract : One of the greatest challenges astronomers are facing today is understanding how galaxies form. We know that the Milky Way is a spiral disk galaxy, similar to many others we see in the sky, therefore the Milky Way is a benchmark for understanding the inner workings of disk galaxies. READ MORE

  6. 10. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Johan Lundberg; [2021]
    Keywords : Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Abstract : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters. READ MORE
