  1. 16. Orientation of plasma jet fronts in the Earth's magnetotail

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Atlas Silverhult; [2023]
    Keywords : Space physics; plamsa; reconnection; magnetospheric multiscale; MMS; magnetosphere; minimum variance analysis; MVA;

    Abstract : This project aims to investigate the orientation of plasma jet fronts in Earth's magnetotail using multi-spacecraft measurement data. The orientations are estimated by applying minimum variance analysis (MVA) and multi-spacecraft timing analysis for finding normal vectors to the jet fronts as they pass over the spacecraft.

  3. 17. Accelerating the Green Transition - Investigating the Feasibility of E-Fuel Production Connected to a CHP Plant

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Johanna Scholtz; Alice Maillard; [2023]
    Keywords : CCU; CHP plant; e-fuels; e-methane; e-methanol; e-kerosene; Technology and Engineering;

    Abstract : The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. READ MORE

  4. 18. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  5. 19. Dynamic response of damped attachments in fighter applications

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

    Author : Katja Nordström; [2023]
    Keywords : Vibration isolator; printed circuit board; vibrations; natural frequency; Vibrationsisolator; kretskort; vibrationer; resonansfrekvenser;

    Abstract : This thesis investigates the impact of vibration isolators on circuit boards during harsh vibrationenvironments that occur when they are mounted on the wings of a fighter jet. To examine thisphenomenon, a mathematical model and a simulated model were developed to determine theresonant frequencies of the circuit board under various boundary conditions. READ MORE

  6. 20. External powder feed

    University essay from Mittuniversitetet/Institutionen för ingenjörsvetenskap, matematik och ämnesdidaktik (2023-)

    Author : Emil Rudh; [2023]
    Keywords : Additive Manufacturing; AM; EBM; Material feeding; PBF; Powder feeding; Additiv tillverkning; AM; EBM; Materialmatning; PBF; Pulvermatning;

    Abstract : Syftet med detta projekt var att undersöka möjligheterna att externt mata in pulver i en PBF-maskin (en EBM-maskin, Electron Beam Melting), för att öka maskinens effektivitet. Huvudmålet med projektet var att designa ett sätt att leverera pulver till byggkammaren från en extern källa. READ MORE
