  1. 16. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
    Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

    Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

  3. 17. Investigating the Electron Reconstruction Efficiency at the LHCb

    University essay from Uppsala universitet/Högenergifysik

    Author : Martin Andersson; [2021]
    Keywords : ;

    Abstract : An exploratory investigation of the electron reconstruction efficiencyat the LHCb is presented. The study is done through simulations ofparticle interaction with the full LHCb detector setup, both by firingsingle particles into the detector and by generating the decay of Bmesons into J/psi K, where the J/psi decays into dileptons.

  4. 18. Optimization of event selection and fake background estimation in a search for heavy scalars in dilepton final states with the ATLAS detector

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Marius Burman Ingeberg; [2021]
    Keywords : Physics; Particle physics; ATLAS; Standard Model; CERN; LHC; Higgs boson; Exotic Higgs Boson; Dilepton final states; Optimization; Physics and Astronomy;

    Abstract : The discovery of the Higgs boson h in 2012 further confirmed the remarkable accuracy of the Standard Model (SM). Despite this, some compelling excesses in multi-lepton final states were recorded in both major runs of the Large Hadron Collider (LHC). READ MORE

  5. 19. Impact of loosening the requirement on missing transverse momentum in tt+DMsearches with the ATLAS experiment

    University essay from Stockholms universitet/Fysikum

    Author : Alice Knutas; [2021]
    Keywords : ;

    Abstract : Dark matter is required in the universe to explain certain phenomenona, like the dynamics of stars and temperature fluctuations of the cosmic microwave background. This thesis focuses on the production of dark matter in the ATLAS experiment at the Large Hadron Collider, where the dark matter is detected through momentum conservation. READ MORE

  6. 20. Investigation of the Effects of Invisible Neutrino Decay at the Proposed ESSnuSB Experiment

    University essay from KTH/Fysik

    Author : Daniel Kempe; [2021]
    Keywords : Neutrino; Decay; Neutrino oscillations; Neutrino oscillation experiment; Neutrino; Sönderfall; Neutrinooscillationer; Neutrinooscillationsexperiment;

    Abstract : This thesis studies neutrino oscillations at the proposed ESSnuSB experiment and the effects of invisible decay, where the neutrino mass states are assumed to be able to decay, on the planned measurements and the physics potential for this experiment to detect neutrino decays. This is accomplished by simulating a combined scenario of neutrino oscillations and invisible neutrino decay. READ MORE
