| Outline of Final Research Achievements |
In this research subject, shape optimizations of small vertical axis wind turbines (VAWT) have been performed with considering uncertainties of operating conditions. We have also performed the comparing investigation of several uncertainty quantification approaches, the development of an efficient geometry parameterization method, and the shape optimization of VAWT with integrating experimental and numerical performance evaluations. Utilizing the developed approaches, robust optimal VAWT shape designs could be efficiently obtained.
