Abstract
Numerical simulations of wind turbines using engineering models for aerodynamic loads are an important design tool. The most common aerodynamic models include the blade element/moment (BEM) method, with numerous corrections for tip loss, hub loss, dynamic stall, and dynamic wake, as well as the generalized dynamic wake (GDW)method, which also employs dynamic stall corrections.
Previous work (Ormberg & Bachynski, 2012) showed that the
differences between such methods have few effects on the global responses of fixed and floating 5 MW wind turbines. The present study proposes a closer examination of the load distribution along the blade of a new 10 MW reference turbine. Three formulations of the aerodynamic load are examined: 1) the BEM model as implemented in AeroDyn (without dynamic wake modeling, but including Beddoes-
Leishman (BL) dynamic stall), 2) the GDW model as implemented in AeroDyn (BL), and 3) the BEM model as implemented in both SIMO and RIFLEX (including Stig Øye's models for dynamic wake and dynamic stall).
