Detailed Summary of the Book

The book is organized into a structured progression of topics, systematically covering fundamental principles before diving into advanced applications. The first chapters introduce the theoretical foundation of wave dynamics in fluids, driven by the governing equations of fluid mechanics such as the Navier-Stokes equations and the equation of continuity. Alongside these, processes like dispersion, non-linearity, and interaction of waves are contextualized for diverse fluid mediums.

The core of the book revolves around computational techniques and numerical methods. Readers will learn classic numerical practices, such as finite-difference methods, finite-volume methods, and spectral methods, with a special focus on their application to solving fluid flow and wave problems. Topics such as the modeling of shock waves using Riemann solvers, the stability and accuracy of numerical schemes, and the handling of boundary conditions are discussed in detail, with numerous practical examples designed to reinforce understanding.

The updated second edition incorporates the latest advances in numerical modeling and includes extended discussions on newer computational methods, like high-resolution and adaptive mesh-refinement techniques. Additionally, the book addresses contemporary challenges in modeling complex fluid behaviors, such as those encountered in geophysical flows, aerodynamics, and acoustics.

The final chapters focus on real-world case studies and practical applications, illustrating how the theory and techniques are applied to solve problems in engineering, environmental science, and meteorology.
