  1. 16. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Soumen Ghosh; [2022]
    Nyckelord :Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Sammanfattning : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. LÄS MER

  3. 17. 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. 18. 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. 19. Undersökning av ny slamutlastning vid ett reningsverk : Analys av flödesförluster och slampump

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Linus Dovnäs; Gustav Edholm; [2022]
    Nyckelord :sludge; sludge pump; sewage; Slam; slampump; reningsverk; flödesförluster; TS-halt; systemkurva; pumpkurva;

    Sammanfattning : A sewage treatment plant is going to get a station in their plant reconstructed. It is the station where the water is separated from the sludge and then transported out of the plant. This new station is the main area for this project. LÄS MER

  7. 20. Establishing a methodology to investigate factors that affect Tip Leakage Loss : In a small scale Organic Rankine Cycle (ORC) turbine

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Anand Ashok Kaushik; [2022]
    Nyckelord :Ansys CFX; CFD; ORC; Turbines; Tip leakage; Internal flow; Loss; Entropy; Correlations;

    Sammanfattning : With growing awareness and necessity for the world to move towards more sustainable (energy saving) forms of power generation, focus on the commercial use of Organic Rankine Cycle (ORC) turbine systems has subsequently increased in turn. ORC systems with their modular design can thus help in recovering heat, obtained as a byproduct from a variety of industrial processes, and thereby increase their overall system efficiency. LÄS MER
