Book Description
The ability to predict and control viscous flow phenomena is becoming increasingly important in modern industrial application. The Instability and Transition Workshop at Langley was extremely important in helpĀ§ ing the scientists community to access the state of knowledge in the area of transition from laminar to turbulent flow, to identify promising future areas of research and to build future interactions between researchers worldwide working in the areas of theoretical, experimental and computational fluid and aero dynamics. The set of two volume contains panel discussions and research contribution with the following objectives: (1) expose the academic community to current technologically important issues of instability and transitions in shear flows over the entire speed range, (2) acquaint the academic community with the unique combination of theoretical, computational and experimental capabilities at LaRC and foster interaction with these facilities. (3) review current state-of-the-art and propose future directions for instability and transition research, (4) accelerate progress in elucidating basic understanding of transition phenomena and in transferring this knowledge into improved design methodologies through improved transition modeling, and (5) establish mechanism for continued interaction.

Book Description
The major objective of the AASERT Grant was to improve the analysis tools as well as assure the level of accuracy and efficiency that can be realized in the study of physics of the dynamic stall and related unsteady phenomena, through the development of the LES/DNS methodology. One M.S. and three Ph. D students were supported partially on this grant. The work carried out consisted of study of external unsteady flow using vorticity stream function formulation, analysis of boundary layer receptivity and transition using DNS methodology with spectral technique and, finally, compressibility effects in maneuvering body flows. Significant accomplishment is made in Object Oriented Numerics and high performance computing.

Book Description
Paperback. The book contains the proceedings of the Colloquium Transitional Boundary Layers in Aeroautics, as organized by the Royal Netherlands Academy of Arts and Sciences on 6-8 December 1995 in Amsterdam.In the external aerodynamics of aircraft, the thin boundary layer along the surface plays an important role. To a large extent, the boundary layer determines the drag of the aircraft. A better knowledge of the laminar-turbulent transition process within the boundary layer may provide technical possibilities for transition control. In this way transition can be postponed, leading to a reduction of the total drag and consequently of the fuel consumption. It is generally recognized that transition belongs to the most difficult problems in fuel mechanics. Fourteen invited papers give an overview of the state-of-the-art of transition phenomena in boundary layers along aircraft surfaces. The emphasis is on the scientific aspects of transition, but resea
