This book was released on 1975 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical solutions of the laminar, incompressible boundary-layer equations are presented for flows involving separation and reattachment. Regular solutions are obtained with an inverse approach in which either the displacement thickness or the skin friction is specified; the pressure is deduced from the solution. A vorticity--stream-function formulation of the boundary-layer equations is used to eliminate the unknown pressure. Solutions of the resulting finite-difference equations, in which the flow direction is taken into account, are obtained by several global iteration schemes which are stable and have unconditional diagonal dominance. Results are compared with Klineberg and Steger's separated boundary-layer calculations, and with Briley's solution of the Navier-Stokes equations for a separated region. In addition, an approximate technique is presented in which the streamwise convection of vorticity is set equal to zero in the reversed flow region; such a technique results in a quick forward-marching procedure for separated flows.

Book excerpt: Interdisciplinary and Advanced Topics in Science and Engineering, Volume 3: Separation of Flow presents the problem of the separation of fluid flow. This book provides information covering the fields of basic physical processes, analyses, and experiments concerning flow separation. Organized into 12 chapters, this volume begins with an overview of the flow separation on the body surface as discusses in various classical examples. This text then examines the analytical and experimental results of the laminar boundary layer of steady, two-dimensional flows in the subsonic speed range. Other chapters consider the study of flow separation on the two-dimensional body, flow separation on three-dimensional body shape and particularly on bodies of revolution. This book discusses as well the analytical solutions of the unsteady flow separation. The final chapter deals with the purpose of separation flow control to raise efficiency or to enhance the performance of vehicles and fluid machineries involving various engineering applications. This book is a valuable resource for engineers.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume entitled "Recent Contributions to Fluid Mechanics" is dedicated to Professor Dr.-Ing. Alfred Walz in honour of his 75th birthday. Alfred Walz, born on 11 May 1907, began his outstanding career as an electrical engineer. A few years after obtaining his university degree he became extremely engaged in fluid dynamics. Walking in the footsteps of Prandtl he was able to direct the development of theoretical activities in an inimitable way. He had the great opportunity to work both as an engaged fluid dynamicist -always trying to get to the bottom of things -and as a popular and patient teacher. To all of these things - in his own words - he gave his heart. Consequently, it is a great pleasure to publish the following 34 contributions summarizing the efforts of 56 authors. These artic les in total cover the wide range of experimental as well as theore tical fluid dynamics and reflect the present state of the art. Moreover, all colleagues and friends of Alfred Walz wish that he may be able to continue his work and his influence on the work of all of us via his enlightening ideas.

This book was released on 2013-06-29 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains 37 contributions in which the research work is summarized which has been carried out between 1984 and 1990 in the Priority Research Program "Physik abgeloster Stromungen" of the Deutsche Forschungsgemeinschaft (DFG, German Research Society). The aim of the Priority Research Program was the inten sive research of the whole range of phenomena associated with separated flows. Physi cal models as well as prediction methods had to be developed based on detailed experi mental investigations. It was in accordance with the main concept of the research program that scientists working on problems of separated flows in different technical areas of application participated in this program. The following fields have been represented in the program: aerodynamics of wings and bodies, aerodynamics of auto mobiles, turbomachinery, ship hydrodynamics, hydraulics, internal flows, heat exchan gers, bio-fluid-dynamics, aerodynamics of buildings and structures. In order to concentrate on problems common in all those areas the emphasis of the program was on basic research dealing with generic geometric configurations showing the fundamental physical phenomena of separated flows. The engagement and enthusiasm of all participating scientists are highly appreciated. The program was organized such that all researchers met once a year to report on the progress of their work. Special thanks ought to go to Prof. E. A. Muller (Gottingen), Prof. H. Oertel jun. (Braunschweig), Dr. W. Schmidt (Dornier), Dr. H. -W. Stock (Dornier) and Dr. B. Wagner (Dornier), who had the functions of referees on those annual meetings.

This book was released on 1983 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new coordinate and variable transformation for the two-dimensional boundary layer equations is presented. The normal coordinate is stretched with a scaling length determined by the local solution. The boundary layer thickness is then essentially constant in computational space for the most types of flows, including separation bubbles and rapidly growing turbulent boundary layers. Similarity solutions can be obtained for all wedge flows. Two finite difference schemes are presented: the Shifted Box Scheme and the Double-Shifted Box Scheme. Both schemes are more resistant to streamwise profile oscillations than the standard Keller's Box Scheme. All governing equations, including the turbulence model, are solved simultaneously as a fully coupled system. This is faster and more robust than conventional weak-coupling iteration schemes. The solution scheme implementation presented makes no restriction on one boundary condition. Any point or integral quantity such as edge velocity, wall shear, displacement thickness, or some functional relationship between two or more of such quantities can be prescribed. The behavior of the boundary layer solution near separation is investigated. It is demonstrated that non-unique solutions always exist whenever an adverse pressure gradient is specified. This bifurcation of the solution is responsible for inability of calculations with prescribed pressure or edge velocity to be carried past separation.
