Summary

This book deals with computational fluid dynamics (CFD) modeling and simulation of materials processing. Papers discuss the modeling of multiscale and multiphase phenomena in material processing systems. The book focuses on the CFD modeling and simulation of metal processes including EMS (electromagnetic stirring) and UST (ultrasonic treatment) controlled melting and solidification processes, advanced casting (including refining of metals, foundry near-net-shape casting, ingot casting, centrifugal casting, continuous casting), forging, welding, heat treating, and VAR/ESR/PAM/EBM remelting processes; coatings including PVD, CVD, and plasma-assisted EBM-PVD technologies; and other surface engineering processes including induction, laser, and EB thermal processing. The book also deals with applications of CFD to engineering processes and demonstrates how CFD can help scientists and engineers to better understand the fundamentals of engineering processes.
