This book presents cutting-edge research from the 14th ERCOFTAC Workshop on Direct and Large Eddy Simulation, offering a unified look at how high-fidelity computational methods are being used to investigate complex flow phenomena across aerodynamics, compressible and multiphase flows, combustion, and turbomachinery. It highlights studies that apply DNS and LES to real-world challenges--such as analyzing vehicle aerodynamics, understanding shock-wave and turbulent boundary-layer interactions, modeling particle-laden flows with advanced data-driven breakage models, and exploring how turbulent spray flames influence nanoparticle synthesis--while also presenting foundational advances in turbulence modeling, statistical analysis, and numerical methods like remeshed vortex techniques.

She has been, and continues to be, a member of the organizing and scientific committees of numerous international conferences (e.g., DLES, ETMM, FRONTUQ, TI series). Her research activity focuses on the study and modeling of complex flows, spanning a wide range of applications, including flow around bluff bodies, microfluidics, cardiovascular flows, wind turbines, and multiphase and reactive flows.
Stefan Hickel is a full professor and chair of Computational Aerodynamics at the Faculty of Aerospace Engineering at Delft University of Technology (TU Delft), the Netherlands. He is also member of the board of the Delft High Performance Computing Centre, associate editor of Computers & Fluids, field editor of the CEAS Aeronautical Journal, and frequent guest editor of Flow, Turbulence and Combustion. At TU Delft, he has served as Director of the Graduate School of Aerospace Engineering and on the Board of Directors of the J.M. Burgerscentrum. After completing three terms as chair of the Scientific Program Committee, he currently serves ERCOFTAC as treasurer and coordinator of the Special Interest Group on Large Eddy Simulation. Professor Hickel is a leading expert in high-fidelity simulation techniques, such as Large-Eddy Simulation (LES) and Direct Numerical Simulation (DNS), which he applies to complex aerodynamic and multiphysics problems. His work addresses fundamental challenges in areas like high-speed compressible flows and high-pressure multiphase flows. A significant part of his work focuses on the development of advanced numerical methods and robust computational models tailored to massively parallel high-performance computing platforms. Professor Hickel has authored numerous publications in prestigious international journals and is an active contributor to the scientific community. His work aims to advance the predictive capabilities of fluid dynamics simulations for next-generation aerospace and energy systems.
Cristian Marchioli is a full professor of Fluid Mechanics at the University of Udine, where he coordinates the Ph.D. 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 the 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.
