Abstract

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, Ahead of Print.
Flow separation frequently occurs in the inboard region of wind turbine blades, leading to degraded aerodynamic performance. A flow deflector (FD) is proposed as a passive flow control approach for wind turbines. The FD consists of a column of small flat ...
