Direct and Large Eddy Simulation XIII Proceedings of DLES13

This book covers the diverse and cutting-edge research presented at the 13th ERCOFTAC Workshop on Direct and Large Eddy Simulation. The first section of the book focuses on Aerodynamics/Aeroacoustics, comprising eight papers that delve into the intricate relationship between fluid flow and aerodynamic performance. The second section explores the dynamics of Bluff/Moving Bodies through four insightful papers. Bubbly Flows, the subject of the third section, is examined through four papers. Moving on, the fourth section is dedicated to Combustion and Reactive Flows, presenting two papers that focus on the complex dynamics of combustion processes and the interactions between fluids and reactive species. Convection and Heat/Mass Transfer are the central themes of the fifth section, which includes three papers. These contributions explore the fundamental aspects of heat and mass transfer in fluid flows, addressing topics such as convective heat transfer, natural convection, and mass transport phenomena. The sixth section covers Data Assimilation and Uncertainty Quantification, featuring two papers that highlight the importance of incorporating data into fluid dynamic models and quantifying uncertainties associated with these models. The subsequent sections encompass a wide range of topics, including Environmental and Industrial Applications, Flow Separation, LES Fundamentals and Modelling, Multiphase Flows, and Numerics and Methodology. These sections collectively present a total of 23 papers that explore different facets of fluid dynamics, contributing to the advancement of the field and its practical applications.

Cristian Marchioli is Associate Professor of Fluid Mechanics at the University of Udine, where he coordinates the PhD program in Energy and Environmental Engineering Sciences. Editor of Acta Mechanica, he is the coordinator of the Marie Sklodowska-Curie Action COMETE (“Next-Generation Computational Methods for Enhanced Multiphase Flow Processes” and served as chairman of the COST Action “Fiber suspension flow modeling”). Currently, Prof. Marchioli sits in the scientific council of the International Center of Mechanical Sciences, where he coordinated several advanced schools on particles in turbulence over the last decade. His research interests involve multiphase flow modeling, from small-scale particle-turbulence interactions to large-scale modeling of gas-solid/gas-liquid flows.

Maria Vittoria Salvetti: Maria Vittoria Salvetti is Professor of Fluid Dynamics at the University of Pisa. She coordinated the Special Interest Group on "Large-Eddy Simulation" (SIG 1) and is chairing the Scientific Programme Committee of the European Research Community on Flow, Turbulence and Combustion. She is associate editor of Computers and Fluids and of Flow, Turbulence and Combustion, and editor of the ERCOFTAC Book Series (Springer). She has been and is currently member of the organizing and scientific committees of many international conferences (e.g., DLES, ETMM, FRONTUQ, TI series). Her research topics involve simulation and modeling, with special focus on Large-Eddy Simulation, of turbulent flows (bluff-body flows, particle-laden flows, wind turbines…), reduced-order models for fluid dynamics, flow instability, flow control, drag reduction, uncertainty quantification and stochastic sensitivity analysis in CFD, micro-fluidics, cardiovascular flows.
