The work shop coincided with the initiation of a new, focused research pro gram on instability and transition at LaRC. The objectives of the workshop were to (i) expose the academic community to current technologically important issues of instability and transition in shear flows over the entire speed range, (ii) acquaint the academic com munity with the unique combination of theoretical, computational and experimental capabilities at LaRC and foster interaction with these facilities, (iii) review current state-of-the-art and propose fu ture directions for instability and transition research, (iv) accelerate progress in elucidating basic understanding of transition phenomena and in transferring this knowledge into improved design methodolo gies through improved transition modeling, and (v) establish mech anisms for continued interaction. The objectives (i) to (iii) were of course immediately met. It is still premature to assess whether ob jectives (iv) and (v) are achieved. The workshop program consisted of tutorials, research presenta tions, panel discussions, experimental and computational demonstra tions, and collaborative projects. There were tutorials on Applica tions of Transition Research (Bushnell), Challenging Research Top ics in Stability and Transition (Morkovin), Initiation and Evolution of Disturbances in Shear Flows (Morkovin), Flight Transition Re search (Holmes), Theoretical Tools (Hall), Measurement Techniques (Gaster), Modeling of Laminar-Turbulent Transition (Narasimha), Laminar Flow Control in Flight Research (Wagner), 3 Ft. Transonic Pressure Tunnel Laminar Flow Control Research (Bobbitt and Har vey), Computational Tools (Zang), and Effects of Flow Quality on Transition (Bobbitt). There were also numerous demonstrations on experimental techniques. Special sessions were devoted to research presentations on Gortler vortices, crossfiow vortices, compressible boundary layer stability. These proceedings contain only panel discussions and the research papers resulting from the collaborative projects started during the workshop and completed shortly thereafter. There were six panels with three to six members in each - the Theory Panel was chaired v by Sir James Lighthill, the Low-Speed Experiment Panel by Percy Bobbitt, the High-Speed Experiment Panel by Dennis Bushnell, the Computation Panel by Steven Orszag, the Receptivity Panel by Eli Reshotko, and the Roughness Panel by Mark Morkovin. The par ticipants of the workshop were divided into several focused groups, each hosted by either a Langley or an ICASE scientist: Experiments (Wilkinson, Dagenhart), Receptivity (Gatski), Advanced Asymp totics (Hall), Boundary Layer Stability (Erlebacher), Free Shear Flows (Macaraeg), Compressible Stability and Transition (Malik), Transi tion Simulation (Zang, Streett), and Transition Modeling (Speziale). The first volume contains the panel summaries and the position papers by the panelists as well as the research papers of the Experi ment Group and the Receptivity Group. The second volume contains the research papers from the remaining groups. The success o~ the workshop was in no small part due to the contributions of the 'indi viduals noted above. We thank all the participants of the workshop for making it such an exciting event. We are deeply grateful to Lee Beach and Roy Harris whose sup port and encouragement was essential from the conception through the execution of the workshop; we are thankful to Richard Barn well and Edwin Prior for their continuous assistance. Then there are many other Langley scientists and logistical staff whose assistance and cooperation contributed to the smooth operation of the work shop. Our thanks are due to them all, in particular Percy Bobbitt, Dennis Bushnell, Douglas Dwoyer, and Manuel Salas. It is a pleasure to express our sincere appreciation to Linda John son and Emily Todd who handled all the preliminary arrangements for the workshop, to Holly Joplin, who served as the workshop secre tarYi and to Etta Blair, who handled reimbursement for the partici pants. We are also appreciative of Emily Todd who coordinated the collection of manuscripts and facilitated their editing, and to Bar bara Stewart who typed the majority of manuscripts. Thanks are also due to Zvi Ruder and other staff of Springer-Verlag for their cooperation in bringing out these volumes. M. Y. Hussaini R. G.
