Instability and Transition : Materials of the Workshop Held May 15–June 9, 1989 in Hampton, Virginia Volume 2

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 Help§ 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.
