Hello, I am investigating the flow around the blades of a Horizontal Axis Wind Turbine while in use for the purpose of identifying how close drones could safely fly. We are hoping that inspection of the blades while they are rotating will be feasible. However, I have not modeled this particular problem before. If anyone has experience modeling the wakes of wind turbines, particularly details within meters or tens of meters of the blades, I would greatly appreciate hearing about your experience. I am particularly interested in

What model you used and why (RANS, LES, DES, etc), what turbulence model, and what the general sizing of your domain and turbine blades were. Did you model a wind farm or a single blade? What computational cost to expect? Any pitfalls to avoid?

Any insights would be appreciated! Thank you!
