Proceedings of the Conference on Improvement of Aerodynamic Performance through Boundary Layer Control and High Lift Systems Held at the Fluid Dynamics Panel Symposium in Brussels, Belgium on 21-23 May 1984.

摘要

There has been an increased experimental understanding of boundary layer structure and behavior particularly in the turbulent regime as well as significant improvements in our knowledge of the factors affecting the boundary-layer transition in arbitrary flow fields. This symposium was intended to bring together the practitioners of the various applications of boundary layer control with those interested in the underlying fluid mechanics. Contributions covered theoretical and experimental developments in the use of both traditional and non-traditional means of boundary layer control for external flow applications such as lift augmentation, drag reduction and improved effectiveness of controls, and for internal flow applications such as air intakes and exit configurations. Techniques included shaping (geometry) suction and blowing; transverse blowing; vortex generators; heating and cooling; and turbulent boundary layer manipulation. The special emphasis on high-lift systems included consideration of the techniques of boundary layer control on characteristics of wings and wing-body arrangements that involve flaps, slats and jets (blown flaps), and vortex flaps.
