Dynamic stall is one of the most complex aerodynamic phenomenon and it affects the perfor- mance of a wide variety of fluid machinery. Previous works show a lack of reliability and accuracy in the development of a stable CFD prediction model. In the present work the purpose is the implementation and validation of a numerical model for an accurate prediction of airloads on a bidimensional airfoil (OA209) under dynamic stall, using the DLR TAU code.

Abstract
Dynamic stall is one of the most complex aerodynamic phenomenon and it affects the perfor- mance of a wide variety of fluid machinery. Previous works show a lack of reliability and accuracy in the development of a stable CFD prediction model. In the present work the purpose is the implementation and validation of a numerical model for an accurate prediction of airloads on a bidimensional airfoil (OA209) under dynamic stall, using the DLR TAU code. Accuracy and reliability are fundamentalFile in questo prodotto:
