  1. 6. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Siddharth Suresh Sumathi; [2023]
    Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE

  3. 7. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Olivia Johansson; [2023]
    Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

    Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE

  4. 8. 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. 9. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    University essay from Umeå universitet/Institutionen för fysik

    Author : Klara Lindroth; [2023]
    Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

  6. 10. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Adam Hjalmarsson; Leon Ericsson; [2023]
    Keywords : 4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Abstract : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.
