Book Description
This 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.

Book Description
This 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.

Book Description
In 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.

Book Description
Accurate 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.

Book Description
PC-Aided Numerical Heat Transfer and Convective Flow is intended as a graduate course textbook for Mechanical and Chemical Engineering students as well as a reference book for practitioners interested in analytical and numerical treatments in the subject. The book is written so that the reader can use the enclosed diskette, with the aid of a personal computer, to systematically learn both analytical and numerical approaches associated with fluid flow and heat transfer without resorting to complex mathematical treatments. This is the first book that not only describes solution methodologies but also provides complete programs ranging from SOLODE to SAINTS for integration of Navier-Stokes equation. The book covers boundary layer flows to fully elliptic flows, laminar flows to turbulent flows, and free convection to forced convection. The student will learn about convection in porous media, a new field of rapid growth in contemporary heat transfer research. A basic knowledge of fluid mechanics and heat transfer is assumed. It is also assumed that the student knows the basics of Fortran and has access to a personal computer.The material can be presented in a one-semester course or with selective coverage in a seminar.
