Dear all,
I want to use AMR-Wind for running Precursor Simulations. These should be used as an input for actuator line-based wind turbine simulations to study the physical phenomena in the near-wake.
I only started working with AMR-Wind, but for me I see two problems coming up.
- Using fully periodic boundary conditions can lead to the locking of large-scale turbulent structures. Using SOWFA/OpenFOAM, I have been able to erase them using shifted boundary conditions as described in Munters et al. (2016). In a previous thread (High and low wind speed streaks in LES simulation of a wind farm - #2 by Jason.Jonkman) it was pointed out, that this approach is not implemented in AMR-Wind yet. Has someone tried to implement this? If so, it would be very nice to get some hints on where to start.
- In my understanding, using the actuator line method for modelling the tower and the nacelle is not sufficient if near-wake phenomena should be studied.
Therefore, I would like to mesh both based on an .stl file. I am a bit scared that trying this could cause problems, as AMR-Wind uses a structured grid. Since I did not find any literature on this question it would be genuinely nice if someone could share his/her experience.
Looking forward for any Input on these points.
Best regards,
Jan
