文摘
- •
Existing post-stall data is demonstrated to be too inaccurate for VAWT analysis.
- •
Two NACA-0012 aerofoils are tested through 180° of incidence.
- •
A blockage tolerant and a conventional wind tunnel test section are used.
- •
Conventional tunnel data requires blockage corrections unsuited to extensively separated flow.
- •
The tolerant tunnel raw data does not need corrections.
