  1. 6. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE

  3. 7. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

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

    Author : Johan Lundberg; [2021]
    Keywords : Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Abstract : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters.

  4. 8. Numerical simulations of mixing for gas exhaust treatment

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Viktor Lahti; [2019]
    Keywords : ;

    Abstract : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. READ MORE

  5. 9. CFD Modeling and Optimization of Primary sedimentation tank

    University essay from KTH/Vattendragsteknik

    Author : Aibin Zhang; [2017]
    Keywords : VOF model; RNG k-ε model; velocity; turbulence; primary sedimentation tank;

    Abstract : In this project, the flow field characteristics of the simplified 2D rectangular primary sedimentation tank in Syvab wastewater treatment plant were achieved by a transient water-air two phases finite-volume method, applying Volume-Of-Fluid (VOF) model. RNG k-ε turbulence model was also employed to calculate the turbulent kinetic energy and its dissipation rate. READ MORE

  6. 10. An experimental study in the near field of a turbulent round free jet

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : JORGE SORBE; [2014]
    Keywords : turbulent; piv; jet;

    Abstract : This work is about the study of the turbulent round jet to low Reynolds number in the outlet of a nozzle due to the countless uses in the industrial field. The objectives of the thesis are the verification of the Particle Image Velocimetry (PIV) data with other methods and authors and the analysis of the near and transition region of the flow. READ MORE
