Synopses & Reviews
This book aims to present modern thinking and developments in the theory, computation and experimental measurement of boundary layers, with particular emphasis on separation. Boundary-layer separation is a common occurrence in external and internal fluid flows at medium to high Reynolds numbers, and the understanding of the phenomenon has increased greatly in recent years. This book, bringing together contributions from theoreticians, computationalists and experimentalists, is an attempt to reflect much of the recent progress as well as point out future goals and provide ideas and stimulation. The work covers the effects of incompressibility and compressibility, steadiness and unsteadiness, two - and three - dimensionality, small - and large - scale behaviour, and various theories, computational methods and experimental findings, for laminar, transitional and turbulent separating flows.
The IUTAM Symposium on Boundary-Layer Separation, suggested by the UK National Committee of Theoretical and Applied Mechanics and supported by the International Union of Theoretical and Applied Mechanics, was held at University College London on August 26-28, 1986. The proposed theme and scope of the Symposium were designed to help to bring about the necessary interaction between experimentalists, computationalists and theoreticians for the furthering of understanding in this challenging subject. The talks and discussions were aimed at representing the very wide range and application of separating-flow phenomena, which often substantially affect the whole of fluid dynamics at medium to large Reynolds numbers, covering in particular both laminar and turbulent flow, steady or unsteady, two- or three-dimensional, small- or large-scale, incompressible or compressible, external or internal, from the experimental, computational and theoretical standpoints. It was intended that about 80 scientists would participate in the Symposium, with about 25 talks being delivered, to which poster sessions with 8 contributions were added subsequently. All the speakers and poster presenters were selected by the scientific committee, although two late replacements of speakers were required. Fruitful discussions, well led by the session chairmen, took place formally after each talk and after the poster sessions and informally on other occasions including the social events. The present proceedings of the Symposium appear to reflect much of the current state of experimental, computational and theoretical work and progress in boundary-layer separation. We hope that they provide also ideas, questions and stimulation, in addition to major recent developments.
