This fourth issue on "progress in turbulence" stems from the fourth ITI conference held in Bertinoro, North Italy, where leading researchers from engineering and physical sciences shared their latest findings. The collection highlights advancements in turbulence research, addressing the notoriously challenging and largely unresolved nature of turbulence. Contributions showcase significant progress in various areas, including enhanced numerical simulations, innovative experimental concepts, and new theoretical frameworks. The relevance of turbulence spans numerous applications, such as combustion, energy, flow control, and urban flows. A key motivation was to connect turbulence fundamentals with renewable energy, leading to a special focus on its impact on wind energy conversion. The book is organized into sections based on topics: I Basic Turbulence Aspects, II Particle Laden Flows, III Modeling and Simulations, IV Experimental Methods, V Special Flows, VI Atmospheric Boundary Layer, VII Boundary Layer, VIII Wind Energy, and IX Convection. This volume is dedicated to the memory of Prof. Tim Nickels, a world-class scientist and cherished member of the turbulence community, who passed away shortly after delivering an invited lecture at the conference.

Besides turbulence there is hardly any other scientific topic which has been considered as a prominent scientific challenge for such a long time. The special interest in turbulence is not only based on it being a difficult scientific problem but also on its meaning in the technical world and our daily life. This carefully edited book comprises recent basic research as well as research related to the applications of turbulence. Therefore, both leading engineers and physicists working in the field of turbulence were invited to the iTi Conference on Turbulence held in Bad Zwischenahn, Gemany 25th - 28th of September 2005. Discussed topics include, for example, scaling laws and intermittency, thermal convection, boundary layers at large Reynolds numbers, isotropic turbulence, stochastic processes, passive and active scalars, coherent structures, numerical simulations, and related subjects.

The term "turbulence” is used for a large variety of dynamical phenomena of fluids in motion whenever the details of the flow appear to be random and average properties are of primary interest. Just as wide ranging are the theoretical methods that have been applied towards a better understanding of fluid turbulence. In this book a number of these methods are described and applied to a broad range of problems from the transition to turbulence to asymptotic turbulence when the inertial part of the spectrum is fully developed. Statistical as well as nonstatistical treatments are presented, but a complete coverage of the subject is not attempted. The book will be of interest to scientists and engineers who wish to familiarize themselves with modern developments in theories of turbulence. The fact that the properties of turbulent fluid flow are addressed from very different points of view makes this volume rather unique among presently available books on turbulence.
