several flow phenomena such as dynamic stall, flow separation, and flow wake deformation,
making the aerodynamic analysis and performance prediction of the Darrieus wind turbine
very difficult. Various computational models exist, each with their own strengths and
weaknesses that attempt to accurately predict the performance of a wind turbine. Being able
to numerically predict wind turbine performance offers a possibility to reduce the expensive
and exhaustive wind tunnel and field experimental tests. The major benefit is that
computational studies are more economical, versatile, and higher resolution than costly
experiments.
