Numerical Computation of Internal and External Flows, Volume 1: Fundamentals of Computational Fluid Dynamics

Detailed Summary of the Book

This book introduces readers to the fundamentals of computational fluid dynamics with meticulous attention to the mathematical, physical, and computational aspects of fluid flow analysis. It is structured to first build a solid understanding of the governing equations in fluid mechanics, including the Navier-Stokes equations, continuity equations, and energy equations.

The book then transitions into numerical strategies for solving these equations. Key numerical techniques such as the finite difference, finite element, and finite volume methods are discussed in detail. Each method is explored with examples that make concepts clear and relatable for practical implementations. Beyond numerical schemes, this book emphasizes their accuracy, stability, and convergence, offering insights into error sources and strategies to minimize them.

In this volume, particular attention is given to both internal flows (such as pipe flows, duct flows, and channel flows) and external flows (such as airflow over an airfoil or around structures). The book not only provides case studies illustrating these flows but also delves into their computational challenges and solutions. As the groundwork for CFD, this text ensures that readers come away with a confident grasp of core principles applicable across various domains of engineering and science.
