This textbook describes the fundamentals of the phenomena of fluid dynamics in the context of engineering instances. It serves as a teaching tool for courses in basic fluid dynamics, advanced fluid dynamics, turbulence, and aerodynamics.

This book gathers the peer-reviewed papers presented at the XXVI Conference of the Italian Association of Theoretical and Applied Mechanics (AIMETA), held in Naples, Italy, on September 2–6, 2024. The conference topics encompass all aspects of general, fluid, solid, and structural mechanics, as well as mechanics for machines and mechanical systems, including theoretical, computational, and experimental techniques and technological applications. As such, the book represents an invaluable, up-to-the-minute tool, providing an essential overview of the most recent advances in the field.

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.

The book surveys the state-of-the-art methods that are currently available to model and simulate the presence of rigid particles in a fluid flow. For particles that are very small relative to the characteristic flow scales and move without interaction with other particles, effective equations of motion for particle tracking are formulated and applied (e.g. in gas-solid flows). For larger particles, for particles in liquid-solid flows and for particles that interact with each other or possibly modify the overall flow detailed model are presented. Special attention is given to the description of the approximate force coupling method (FCM) as a more general treatment for small particles, and derivations in the context of low Reynolds numbers for the particle motion as well as application at finite Reynolds numbers are provided. Other topics discussed in the book are the relation to higher resolution immersed boundary methods, possible extensions to non-spherical particles and examples ofapplications of such methods to dispersed multiphase flows.
