The turbulent/non-turbulent interface (TNTI) is an irregular boundary between turbulent and irrotational flow, which widely exists in various flow types, such as turbulent boundary layer, combustion flame front, turbulent patches in atmosphere and ocean, pollutant dispersion, etc. Due to its importance in affecting the intermittent characteristic and the mixing and entertainment process of turbulent flows, TNTI has become one of the most active branches of turbulent research in the past decades. Nevertheless, the scientific community still faces various challenges that hinder an ultimate characterization and modelling of TNTI. The unresolved problems, to name a few, spread from the lack of a well-accepted definition of TNTI to the intriguing origin of its fractal multi-scale nature. The dynamics of TNTI, which is the key for the mechanism of the exchange of mass, momentum and energy between turbulence and irrotational outflows, also deserves an interpretation from the perspective ofturbulent structures.
This book presents the proceedings of the "IUTAM Symposium on turbulent/non-turbulent interface in turbulent shear flow' will be held in 2024, Oct. This book will collect the up-to-date works from active researchers worldwide to anchor the state-of-art knowledge of TNTI and to envision the future direction of this field. The focus includes but is not limited to the scaling for the geometries, kinematics and dynamics of TNTI, the role of turbulent structures in the entrainment process, multiphase flow with TNTI, high-fidelity turbulent model that accounts for the intermittency of TNTI, and reduce-order-model-based prediction for engineering application. The content is a valuable reference for researchers, engineers and students who are interested in understanding the complex behavior of TNTI in turbulent shear flows. This is an open access book.
Professor Jinjun Wang has published more than 300 peer-reviewed journal papers, more than 180 indexed by SCI, and given more than 10 times invited lectures in international conferences. He was invited to write the book titled "Flow Control Techniques and Applications", which was the first monograph from China being included in Cambridge University Press Aerospace Series. The American Society of Mechanical Engineers recommended the book as one of the 11 best new books in engineering in 2019. Prof. Wang has been successively selected as one of the most cited scholars by Elsevier. He was invited twice to write review articles for Progress in Aerospace Sciences, and was the first Chinese scholar to publish an article in this journal.
Ivan Marusic is an ARC Laureate Fellow and Professor in the Department of Mechanical Engineering at the University of Melbourne. He received his PhD in 1992 and BE (Hons) Mech in 1987 from the
University of Melbourne. His research isprimarily in experimental and theoretical studies of turbulence at high Reynolds numbers. This includes studies in atmospheric surface layer flows and aquatic ecosystems. Prior to arriving in Melbourne in 2007 as an ARC Federation Fellow he was a faculty member at the University of Minnesota, where he was a recipient of an NSF Career Award and a Packard Fellowship in Science and Engineering. He is a Fellow of the Australian Academy of Science and the American Physical Society, an Associate Editor of the Journal of Fluid Mechanics and the Journal of Hydraulic Research.
