Numerical analysis of transonic flow over the FFA-W3-211 wind turbine tip airfoil [PDF]

open access: yesWind Energy Science
Modern wind turbines are the largest rotating machines ever built, with blade lengths exceeding 100 m. Previous studies demonstrated how the flow around the tip airfoils of such large machines reaches local flow Mach numbers (Ma), at which the ...
