  1. 1. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

    University essay from KTH/Kraft- och värmeteknologi

    Author : Ettore Scami; [2022]
    Keywords : Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

    Abstract : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. READ MORE

  3. 2. Optimizing Energy System in a Supermarket : A case study analysis

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