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.
Boundary Layer Theory is a comprehensive introduction to the physics of the boundary layer, and the latest numerical methods for describing it. The increases in computing power of recent decades have expanded our capability to investigate complex fluid phenomena such as boundary layer turbulence, and research in this field has lead to important advances for aerospace, chemical, thermal, and hydraulic engineering among other areas.With worked examples and problem exercises in every chapter, this book helps readers to understand the physics of the boundary layer before going through the related numerical solutions, and moving on to the latest numerical methods as they are used in research globally.Topical research areas such as non-Newtonian fluid-boundary layers, effects of magnetohydrodynamics on boundary layers, and three dimensional boundary layer effects are all addressed, making this the ideal starting point for any fluids engineer approaching a research topic in boundary layer.
Numerical Methods in Turbulence Simulation provides detailed specifications of the numerical methods needed to solve important problems in turbulence simulation. Numerical simulation of turbulent fluid flows is challenging because of the range of space and time scales that must be represented. This book provides explanations of the numerical error and stability characteristics of numerical techniques, along with treatments of the additional numerical challenges that arise in large eddy simulations. Chapters are written as tutorials by experts in the field, covering specific both contexts and applications. Three classes of turbulent flow are addressed, including incompressible, compressible and reactive, with a wide range of the best numerical practices covered. A thorough introduction to the numerical methods is provided for those without a background in turbulence, as is everything needed for a thorough understanding of the fundamental equations. The small scales that must be resolved are generally not localized around some distinct small-scale feature, but instead are distributed throughout a volume. These characteristics put particular strain on the numerical methods used to simulate turbulent flows.
