Although much employed, wind energy systems still present an open, contemporary topic of
many research studies. Special attention is given to precise aerodynamic modeling performed in
the beginning since overall wind turbine performances directly depend on blade aerodynamic
performances. Several models different in complexity and computational requirements are still
widely used. Most common numerical approaches include: i) momentum balance models, ii)
potential flow methods and iii) full computational fluid dynamics solutions.
Short explanation, review and comparison of the first two simpler computational categories
are given in the paper. Since potential flow methods generally produce better and more
comprehensive results (with more physical details taken into account) than momentum-based
models, they are studied with more attention. Algorithms of all considered numerical approaches
are implemented and presented. Results including global parameters such as thrust and power
...coefficients as well as local distributions along the blade obtained by different models are
compared to available experimental data. Knowledge and experience gained while coding the
models are summed in the final section (Conclusions).
