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.

Shu-Qing Yang obtained his PhD from Nanyang Technological University, Singapore, and is currently Associate Professor in the School of Civil, Mining and Environmental Engineering at the University of Wollongong, NSW, Australia. Prior to this appointment, he was Professor and Chair Professor in Korea Maritime University and South China University of Technology, respectively. His research interests include fluid mechanics, hydraulics, sediment transport, drag-reduction with polymer additives, and water resources engineering. He was a chief investigator for sedimentation problems in the Three Gorges Dam, one of the largest dams in the world. He also helped the initiation of coastal reservoirs in many countries including Shanghai, Chinaone of the megacities with severe water shortage caused by pollution.
