  1. 1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

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

    Author : Erik Fridén; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

  2. 2. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  3. 3. Error propagation in nuclear models

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Artis Mucenieks; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  4. 4. Thermal Analysis of Wave Energy Converter : Developing a Compact CHT Model for Operational Insights

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jakob Jidbratt; Joel Leckström; [2023]
    Keywords : Computational Fluid Dynamics; CFD; Conjugate Heat Transfer; CHT; Wave Energy Converter; WEC; Moving mesh; Ball screw;

    Abstract : Climate change is a critical global issue that continues to shape the way we understand and interact with the world around us. It is discussed more than ever before, especially in politics. READ MORE

  5. 5. Assessing Sweden's future prospect for domestic hydrogen production based on lifecycle assessment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fredrik Tannoury; [2022]
    Keywords : Technology Readiness Level; Hydrogen production; LCA; Sweden;

    Abstract : Humanity faces challenge to satisfy its growing energy demand while simultaneously transitioning into a sustainable society. Reducing carbon emissions from the industrial and transportation sector are met with difficulties. To help decarbonisation efforts EU members like Sweden have recognised the use of hydrogen as a viable solution. READ MORE
