An introductory lecture will discuss the importance of drag prediction for aircraft design and give an overview of the major factors involved in CFD-based drag prediction, which will be covered in detail in subsequent lectures. Novel methods for drag evaluation and decomposition from CFD solutions will be presented, as well as the latest advances of the wake integration method for drag prediction from wind tunnel tests.
The state-of-the-art of drag prediction capabilities of flow solvers using both multi-block structured grid and unstructured grid technology will be discussed. The important problem of turbulence modelling will be reviewed, including recent developments of non-linear eddy viscosity models. The related subject of transition modelling will be covered also. Finally the development of adjoint based design optimization methods will be discussed.
Applications will focus mainly on the subsonic and transonic flight regimes of transport aircraft, including particular topics such as the design of high lift systems and engine/airframe integration.
The directors of this course are Prof. H. Deconinck and Ir. K. Sermeus of the von Karman Institute, and Prof. C. van Dam of UC Davis, California, USA.
