Synopsis

The origins of turbulent ?ow and the transition from laminar to turbulent ?ow are the most important unsolved problems of ?uid mechanics and aerodynamics. - sides being a fundamental question of ?uid mechanics, there are numerous app- cations relying on information regarding transition location and the details of the subsequent turbulent ?ow. For example, the control of transition to turbulence is - pecially important in (1) skin-friction reduction of energy ef?cient aircraft, (2) the performance of heat exchangers and diffusers, (3) propulsion requirements for - personic aircraft, and (4) separation control. While considerable progress has been made in the science of laminar to turbulent transition over the last 30 years, the c- tinuing increase in computer power as well as new theoretical developments are now revolutionizing the area. It is now starting to be possible to move from simple 1D eigenvalue problems in canonical ?ows to global modes in complex ?ows, all - companied by accurate large-scale direct numerical simulations (DNS). Here, novel experimental techniques such as modern particle image velocimetry (PIV) also have an important role. Theoretically the in?uence of non-normality on the stability and transition is gaining importance, in particular for complex ?ows. At the same time the enigma of transition in the oldest ?ow investigated, Reynolds pipe ?ow tran- tion experiment, is regaining attention. Ideas from dynamical systems together with DNS and experiments are here giving us new insights.

About this title

Product Description:

The dynamics of transition from laminar to turbulent flows remains to this day a major challenge in theoretical and applied mechanics. The subject is of significance in diverse areas like gas turbines, underwater applications, flow control etc. This volume will contain approximately 100 papers on flow instability, transition to turbulence, flow control, etc., of presentations made during the seventh IUTAM symposium on laminar-turbulent transition, Stockholm, Sweden, 2009. It thus equips the reader with the latest in research in this area. For the present volume, the areas of emphasis are: Novel approaches to receptivity analysis and transition modeling, Non-normal effects and global modes, Stability of complex flows, such as non-Newtonian and miscible-interface flows, Transition in simple shear flows and its relation to properties of non-linear dynamical systems, Modern feedback control and design techniques applied to transition, Transition in high-speed flows, Direct and Large-Eddy Simulation of transition, Applied Laminar Flow Control.

From the Back Cover:

The origins of turbulent flow and the transition from laminar to turbulent flow are the most important unsolved problems of fluid mechanics and aerodynamics. Besides being a fundamental question of fluid mechanics, there are numerous applications relying on accurate information regarding transition location and the details of the subsequent turbulent flow. While considerable progress has been made in the understanding of laminar-turbulent transition over the last 30 years, the continuing increase in computer power as well as new theoretical developments are now revolutionizing the area.

This volume contains 110 papers of presentations delivered during the "Seventh IUTAM Symposium on Laminar-Turbulent Transition" in Stockholm, Sweden, June 2009. The areas of emphasis include:

Novel approaches to receptivity analysis and transition modelling.

Non-normal effects and global modes.

Stability of complex flows, such as non-Newtonian and miscible-interface flows.

Transition in simple shear flows and its relation to properties of non-linear dynamical systems.

Modern feedback control and design techniques applied to transition.
