  1. 21. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  3. 22. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jean-Pierre Hamzo; [2023]
    Keywords : CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Abstract : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. READ MORE

  4. 23. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

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

    Author : Þóra Karlsdóttir; [2023]
    Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

  5. 24. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Annachiara Nardone; [2023]
    Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE

  6. 25. Atomic Structure Calculations Using Configuration-Interaction And Many-Body Perturbation Theory For Spectral Modelling Of Neutron Star Mergers : Example Of Ce I - Iv

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Fredrik Plane; [2023]
    Keywords : Computational atomic physics; Atomic physics; Physics; Astronomy; Astrophysics; Neutron stars; Stars; Relativisitc atomic physics; Configuration-interaction; Perturbation theory; Many-body perturbation theory;

    Abstract : The binary neutron star merger of 2017 and its corresponding electromagnetic signature resembling that of a kilonova has been one of the most groundbreaking astrophysical occurrences in the last decade. Indications of r-process nucleosynthesis in this event presents new opportunities for learning about the astrophysical origin of heavy elements. READ MORE
