Journal Article
Experimental benchmark and code validation for airfoils equipped with passive vortex generators
Daniel Baldacchino,Marinos Manolesos,C.J. Simao Ferreira,A. González Salcedo,M. Aparicio,T. Chaviaropoulos,Konstantinos Diakakis,Liesbeth Florentie,Miriam García,George Papadakis,Niels N. Sørensen,W.A. Timmer,Niels Troldborg,Spyros G. Voutsinas,A.H. van Zuijlen +14 more
TL;DR: Comparisons of experimental results and complimentary computations for airfoils with vortex generators are compared and indicate that with appropriate calibration, engineering-type tools can capture the effects of vortex generators and outperform more complex tools.
Journal ArticleDOI
Experimental benchmark and code validation for airfoils equipped with passive vortex generators
Daniel Baldacchino,Marinos Manolesos,Célia Maria Dias Ferreira,A. González Salcedo,M. Aparicio,T. Chaviaropoulos,Konstantinos Diakakis,Liesbeth Florentie,Néstor Ramos García,George Papadakis,Niels N. Sørensen,N. Timmer,Niels Troldborg,Spyros G. Voutsinas,A.H. van Zuijlen +14 more
TL;DR: In this paper, experimental results and complimentary computations for airfoils with vortex generators are compared, as part of an effort within the AVATAR project to develop tools for wind turbine blade control devices.

TL;DR: In this article, the results of a blind test campaign organized in the AVATAR project to predict the high Reynolds number performance of a wind turbine airfoil for wind turbine applications are summarized.
Journal ArticleDOI
Assessment of transition modeling for high Reynolds flows
TL;DR: In this article, the e N method and the γ- R e θ transition model are thoroughly evaluated against measured data obtained for four airfoils in conditions that range from R e = 3 to 40 millions.
Journal ArticleDOI
