Some good info here, more than the EVM site. Hard to navigate via my phone. There is probably a whole research paper on this somewhere.

Main take away for me is the theoretical modelling and small scale wind tunnel modelling is very close to reality. That means a very good confidence level that the full scale tower will perform as simulations and modelling predict. Rest assured that the modelling has improved significantly since this tower was operating.
