SHOCK WAVE–BOUNDARY-LAYER INTERACTIONS

Shock wave–boundary-layer interaction (SBLI) is a fundamental phenomenon in gasdynamics that is observed in many practical situations, ranging from transonic aircraftwings to hypersonic vehicles and engines. SBLIs have the potential to pose serious prob-lems in a flowfield; hence they often prove to be critical – or even design-limiting – issuesfor many aerospace applications.

This is the first book devoted solely to a comprehensive state-of-the-art explanationof this phenomenon with coverage of all flow regimes where it occurs. The book includesa description of the basic fluid mechanics of SBLIs plus contributions from leading inter-national experts who share their insight into their physics and the impact they have inpractical flow situations. This book is for practitioners and graduate students in aerody-namics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuableresource for specialists because it compiles experimental, computational, and theoreticalknowledge in one place.

Holger Babinsky is Professor of Aerodynamics at the University of Cambridge and aFellow of Magdalene College. He received his Diplom-Ingenieur (German equivalent ofan MS degree) with distinction from the University of Stuttgart and his PhD from Cran-field University with an experimental study of roughness effects on hypersonic SBLIs.From 1994 to 1995, he was a Research Associate at the Shock Wave Research Centreof Tohoku University, Japan, where he worked on experimental and numerical investi-gations of shock-wave dynamics. He joined the Engineering Department at CambridgeUniversity in 1995 to supervise research in its high-speed flow facilities. Professor Babin-sky has twenty years of experience in the research of SBLIs, particularly in the develop-ment of flow-control techniques to mitigate the detrimental impact of such interactions.He has authored and coauthored many experimental and theoretical articles on high-speed flows, SBLIs, and flow control, as well as various low-speed aerodynamics subjects.Professor Babinsky is a Fellow of the Royal Aeronautical Society, an Associate Fellowof the American Institute of Aeronautics and Astronautics (AIAA), and a Member ofthe International Shock Wave Institute.

Recently, in collaboration with the U.S. Air Force Research Lab-oratories, he organized the first AIAA workshop on shock wave–boundary-layer predic-tion. He has developed undergraduate- and graduate-level courses in Fluid Mechanicsand received several awards for his teaching.
