Book Description
Equations for the asymptotic flow due to passage of a shock through a constriction are presented. The region of ambiguity which involved 3 possible solutions with either a reflected shock, a standing shock, or no shock, is reviewed. A wave diagram is constructed to show that the solution involving no reflection is unstable under a small but finite disturbance. Kantrowitz's perturbation equations for non-steady, one-dimensional flow through a particular, non-uniform, nozzle are used to investigate the problem of shock formation due to expansion-disturbances. Two problems are considered: the first is a complete treatment of shock formation in a de Laval nozzle; the second is the case of shock formation in a decelerating supersonic flow. Results of the second case are then used to formulate a criterion for the stability of the solution for flow through a constriction without a reflected shock, under action of a small disturbance.

Book Description
Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.
