Development of the Pressure-Time as a Relative Method
Njølstad Dagsvik, Helene (Master thesis, 2017)Hydropower has played an essential role in the Norwegian power production over the last century. Approximately 99.9 % of the total production comes from renewable sources, of which hydropower represent 99 %. Changes in ... -
Numerical investigation of tip leakage vortex
Fredriksen, Vegard (Master thesis, 2017)The Kaplan turbine has a small clearance gap between the blade tip and casing to allow the blades to rotate freely. This clearance gap is the cause of an undesirable Tip Leakage Vortex (TLV). A TLV might reduce the turbine ... -
Numerical simulation of air injection in Francis turbines
Pitorac, Livia-Ioana (Master thesis, 2017)With the increasing use of renewable energy such as wind and solar, the power market operation is changing. The energy producers using classic resources have to adapt. This applies to hydropower plants as well, which are ... -
Transient CFD-analysis of a high head Francis turbine
Moritz, Ruben Arne Christoph (Master thesis, 2014)The purpose of the present work has been to investigate how well transformation methods work as a method to get realistic inlet boundary conditions to a draft tube without using excessive amounts of computational resources. ...
