1. 11. Verification of the fluid dynamics modules of the multiphysics simulation framework MOOSE : A work to test a candidate software for molten salt reactor analysis

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Erik Gustafsson; [2022]
   Nyckelord :molten salt reactor MSR ; small modular reactor SMR ; computational fluid dynamics CFD ; multiphysics; MOOSE;

   Sammanfattning : This is a report of a verification study of the multiphysics simulation framework MOOSE which was preformed at the company Seaborg Technologies. In the process of designing molten salt reactors there is a special need of making credible multiphysics simulations since the fuel is in motion. LÄS MER

3. 12. Simulation strategies for improved contamination modeling of liquid dynamics on automotive surfaces

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Thisal Mandula Sugathapala; Twan Bakker; [2022]
   Nyckelord :Volume of Fluid; Contamination modeling; Blended Kistler model; Dynamic contact angle models; Exterior water management; Light-induced fluorescence imaging; Multiphase flows; Surface flows; Computational fluid dynamics; Sensor soiling;

   Sammanfattning : A significant level of research is currently being carried out in the development of driver support systems as they are expected to play a key role in minimizing road vehicle accidents and creating a safe driving environment under harsh weather conditions. However, the performance of some components used by existing driver support systems like LIDAR and visual cameras are affected by extreme weather conditions such as heavy rain fall and snow. LÄS MER

4. 13. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Aryan Delir; [2022]
   Nyckelord :gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

   Sammanfattning : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

5. 14. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Lea Christierson; [2021]
   Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

   Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER

7. 15. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Mahim Ahsan; [2021]
   Nyckelord :;

   Sammanfattning : The importance of aerodynamics in racing has increased substantially over the past decades. Racing vehicles utilize different aerodynamic devices, to redirect the airflow around the vehicle in a beneficial way. The increase in downforce using an aerodynamic wing package increases drag force. LÄS MER
