DOWNLOAD EBOOKIn 1904 Prandtl published the boundary layer equations and, thereby, firmly stamped the direction of research in fluid mechanics for the next sixty-five years. In Aerodynamics especially (a discipline that is intrinsically concerned with non -recirculating flows) the decomposition of the flow into an inviscid region bounded, near rigid surfaces, by thin viscous zones, proved such a powerful stimulus that it sustained decades of outstandingly successful theoretical and experimental work. Yet, in contrast, only a relatively small proportion of the flows in and around Mechanical Engineering equipment are reasonably well described by the thin shear flow equations. Commonly flow recirculations are present, particularly in heat transfer equipment where a judiciously provoked separation is often found to raise substantially the level of heat transfer coefficient. Because the equations describing such flow phenomena are much more difficult to solve than the boundary layer equations, the contributions made by computational fluid mechanics to the design of Mechanical Engineering equipment has been correspondingly less than in Aeronautics. By 1970 the predominance of thin shear flow studies had begun to weaken and the ensuing decade has seen a steady development of computational procedures for recirculating flow and the essential supporting experimental techniques. Although considerable progress has been made, however, it is clear that we are still nearer the beginning than the end in providing the necessary fundamental research basis in this area. Accordingly, to provide both a forum for airing current work and a springboard for further research, the K-8 Committee of the Heat Transfer Division decided to sponsor a session at the 1980 WAM on Momentum and Heat Transfer in Recirculating Flows. In fact, the response to the announcement of the session was so vigorous that two sessions have been scheduled at which the twelve papers contained in the present volume are to be presented. The papers span many of the current areas of work including: both computational and experimental studies; laminar and turbulent flows; and both steady and unsteady flow phenomena.

DOWNLOAD EBOOKThis volume collects various contributions from the 5th International Conference on Jets, Wakes and Separated Flows (ICJWSF2015) that took place in Stockholm during June 2015. Researchers from all around the world presented their latest results concerning fundamental and applied aspects of fluid dynamics. With its general character, the conference embraced many aspects of fluid dynamics, such as shear flows, multiphase flows and vortex flows, for instance. The structure of the present book reflects the variety of topics treated within the conference i.e. Jets, Wakes, Separated flows, Vehicle aerodynamics, Wall-bounded and confined flows, Noise, Turbomachinery flows, Multiphase and reacting flows, Vortex dynamics, Energy-related flows and a section dedicated to Numerical analyses.

DOWNLOAD EBOOKThis book presents and discussses new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. At present, turbulence is one of the key issues in tackling engineering flow problems. Powerful computers and numerical methods are now available for solving the flow equations, but the simulation of turbulence effects which are nearly always important in practice, is still in an unsatisfactory state and introduces considerable uncertainities in the accuracy of CFD calculations. These and other aspects of turbulence modelling and measurements are dealt with in detail by experts in the field. The resulting book is an up-to-date review of the most recent research in this exciting area.

DOWNLOAD EBOOKAccurate prediction of turbulent flows remains a challenging task despite considerable work in this area and the acceptance of CFD as a design tool. The quality of the CFD calculations of the flows in engineering applications strongly depends on the proper prediction of turbulence phenomena. Investigations of flow instability, heat transfer, skin friction, secondary flows, flow separation, and reattachment effects demand a reliable modelling and simulation of the turbulence, reliable methods, accurate programming, and robust working practices. The current scientific status of simulation of turbulent flows as well as some advances in computational techniques and practical applications of turbulence research is reviewed and considered in the book.

DOWNLOAD EBOOKWith major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, this two-volume handbook presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the field, along with critical discussions of environmental sustainability related to engineering aspects. The first volume provides a comprehensive overview of the fundamentals, and the second volume explores the interactions between engineered structures and natural flows.
