VKI Lecture Series
Ever since the very beginning of aerodynamic flight, the accurate prediction of aerodynamic drag has been a major challenge in the aircraft design process. During the past 20 years, Computational Fluid Dynamics (CFD) has come to play an increasingly important role in this respect, but significant advances in CFD modelling capabilities are still needed. Future improvements in performance of transport aircraft (notably fuel efficiency and hence direct operating costs), will largely depend on reducing aerodynamic drag. This will be achieved by design optimization and technologies such as laminar flow control, areas in which CFD will play a vital role.
The objective of this Lecture Series is therefore to present the state-of-the-art and current research directions in CFD-based drag prediction. The course is aimed at applied aerodynamicists and CFD researchers as well as aircraft designers.
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.
