Near-Boundary Fluid Mechanics focuses on the near-boundary region and its significance. It delves into topics like boundary shear stress, drag reduction using polymer additives, turbulence sources, secondary currents, log-law validity, sediment transport, and more. Unlike similar books, it emphasizes the importance of the near-boundary region. This book is organized into chapters covering internal flows, external flows, loose boundary flows, and density currents. It extends Prandtl's fundamental concept to internal flows, showing how potential flow theory can describe flow without a solid boundary.In addition, the book provides a theoretical analysis of boundary shear stress in three-dimensional flows and explores the turbulent structures in drag-reduction flows. A key feature is clarifying the role of wall-normal velocity in mass, moment, and energy transfer. Additionally, Archimedes' principle is covered to explain pressure drag and establishes a relationship between wake volume and hydrodynamic force.
