    • Application of Three-Dimensional CFD Model to Determination of the Capacity of Existing Tyrolean Intake 

      Bor Turkben, Asli; Szabo-Meszaros, Marcell; Vereide, Kaspar Vatland; Lia, Leif (Journal article; Peer reviewed, 2024)
      CFD models of intakes in high-head hydropower systems are rare due to the lack of geometric data and cost of modeling. This study tests two different types of software to see how modeling can be performed in a cost-effective ...

    • Direct Simulation of Surge Tank Stability 

      Bardini, Debora (Master thesis, 2018)
      This thesis deals with the issue of surge tank stability in hydropower plants, investigating methods used to design the surge tank area required to guarantee stability. Currently, Thoma equation (1910) is widely accepted ...

    • Hydraulic Scale Modelling of Dam Breaks 

      Bogati, Pritam (Master thesis, 2024)
      Denne studien undersøker dambruddbølger ved bruk av hydraulisk skalamodellering og analytiske metoder for å evaluere mulige effekter av et lite dambrekk ved Tonstad vannkraftverk i Norge. En forvrengt skalamodell ble bygget ...

    • Hydraulic Transient Impact on Surrounding Rock Mass of Unlined Pressure Tunnels 

      Ghimire, Sanyam; Panthi, Krishna Kanta; Vereide, Kaspar Vatland (Peer reviewed; Journal article, 2023)
      The frequent pressure pulsations due to hydraulic transients in hydropower plants induce cyclic loading on the rock mass that may contribute to increased instances of block falls and increased risk of tunnel collapse over ...

    • Hydraulics and Thermodynamics of Closed Surge Tanks for Hydropower Plants 

      Vereide, Kaspar Vatland (Doctoral thesis at NTNU;2016:20, Doctoral thesis, 2016)
      This work has studied the hydraulic and thermodynamics of closed surge tanks for hydropower plants. Surge tanks are applied in hydropower plants to control and reduce the acceleration forces of the water during change of ...

    • Long-term impact on unlined tunnels of hydropower plants due to frequent start/stop sequences 

      Neupane, Bibek (Doctoral theses at NTNU;2021:400, Doctoral thesis, 2021)
      Abstract The concept of unlined pressure tunnel design is well-tested and has a history of more than 100 years. In Norway, more than 95% of hydropower pressure tunnels are unlined and most of it was built between 1950 ...

    • Practical Experiences from Application of a Comprehensive Simulator for Pumped Storage Hydropower Investment Decisions on a Real Investment Case 

      Schüller, Kristine; Aaslid, Per; Vereide, Kaspar Vatland; Skjelbred, Hans Ivar (2024 20th International Conference on the European Energy Market (EEM);, Chapter, 2024)
      The future electricity system is expected to include a higher share of production from renewable energy sources. This will lead to increased price volatility and thus a higher demand for short-term balancing by hydropower ...

    • Testing av luftmedrivning på flomløp Follsjødammen 

      Brøste, Karoline Mittet (Master thesis, 2017)
      Formålet med masteroppgaven har vært å studere luftmedrivning i modellen av det lukkede flomløpet ved dam Follsjøen i Rindal kommune. Modellen er opprinnelig bygget for et modellforsøk av flomavledningskapasiteten, men er ...
