  1. 1. Thermal degradation of PFAS in solid matter

    University essay from KTH/Kemi

    Author : Tuqa Al-Badri; [2024]
    Keywords : PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

    Abstract : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. READ MORE

  3. 2. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

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

    Author : Lukas Jönsson; [2023]
    Keywords : Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Abstract : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  4. 3. Convolution-compacted visiontransformers forprediction of localwall heat flux atmultiple Prandtlnumbers in turbulentchannel flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yuning Wang; [2023]
    Keywords : Turbulent flow; Heat transfer; Vision transformer; Convolutional neural network; Machine learning;

    Abstract : Predicting wall heat flux accurately in wall-bounded turbulent flows is critical for a variety of engineering applications, including thermal management systems and energy-efficient designs. Traditional methods, which rely on expensive numerical simulations, are hampered by increasing complexity and extremly high computation cost. READ MORE

  5. 4. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gusten Zandler Andersson; [2023]
    Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE

  6. 5. Quantum signatures in the work fluctuation-dissipation relation protocol

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

    Author : Jian Li; [2023]
    Keywords : Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Abstract : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. READ MORE
