    • FSI-analysis of a Francis turbine 

      Bergmann-Paulsen, Jonas (Master thesis, 2012)
      Sediment erosion in Francis turbines is a big problem in hydropower plants in and around the Himalayas. The sediment composition in the rivers contains high levels of the hard mineral quarts. When the sediments enter the ...

    • Hydraulic Design of Francis Turbine Exposed to Sediment Erosion 

      Gjøsæter, Kristine (Master thesis, 2011)
      Sediment erosion is a large problem for turbines operated in sand laden water, especially in the Himalayas and the Andes Mountains, where the contents of hard minerals in the rivers are high. A program called RenewableNepal ...

    • Sediment Erosion in Francis Turbines 

      Eltvik, Mette (Master thesis, 2009)

    • Sediment Erosion in Francis Turbines 

      Eltvik, Mette (Master thesis, 2009)
      The high concentration of sediments in the rivers near the Andes and the Himmalayas, is a large problems for run-of-river power plants. Small particles of quartz, which is a hard and sharp mineral, damage the turbine and ...

    • Sediment erosion in Francis turbines 

      Eltvik, Mette (Doktoravhandlinger ved NTNU, 1503-8181; 2013:250, Doctoral thesis, 2013)
      Sediment erosion is a major challenge for run-of-river power plants, especially during flood periods. Due to the high content of hard minerals such as quartz and feldspar carried in the river, substantial damage is observed ...
