A test of the v 2-f k-epsilon turbulence model for the prediction of vortex shedding in the Francis-99 hydrofoil test case
Sagmo, Kristian Forfot; Storli, Pål-Tore Selbo (Journal article; Peer reviewed, 2019)A test of the v 2 − f k − epsilon turbulence model for the flow around the Francis-99 hydrofoil geometry is conducted in order to assess it's accuracy of trailing edge vortex shedding prediction. The model is based on the ... -
Performance of the NREL S826 airfoil at low to moderate Reynolds numbers — A reference experiment for CFD models
Bartl, Jan Michael Simon; Sagmo, Kristian Forfot; Bracchi, Tania; Sætran, Lars Roar (Journal article; Peer reviewed, 2019)Lift, drag and surface pressure measurements are performed on a wing section of the NREL S826 wind turbine airfoil at eight Reynolds numbers ranging from 0:5_105 to 6:0_105. Alongside with the measurements two types of ... -
Trailing edge vortex shedding in hydraulic turbines and the effect of stream-wise vorticity on vortex induced vibrations
Sagmo, Kristian Forfot (Doctoral theses at NTNU;2021:42, Doctoral thesis, 2021)Experiments as well as some numerical simulations were conducted investigating the resonance region of vortex induced vibrations for different trailing edges of a hydrofoil in channel flow. The study focuses on the ...
