Covered from the vantage point of a user of a commercial flow package, Essentials of Computational Fluid Dynamics provides the information needed to competently operate a commercial flow solver. This book provides a physical description of fluid flow, outlines the strengths and weaknesses of computational fluid dynamics (CFD), presents the basics of the discretization of the equations, focuses on the understanding of how the flow physics interact with a typical finite-volume discretization, and highlights the approximate nature of CFD. It emphasizes how the physical concepts (mass conservation or momentum balance) are reflected in the CFD solutions while minimizing the required mathematical/numerical background. In addition, it uses cases studies in mechanical/aero and biomedical engineering, includes MATLAB and spreadsheet examples, codes and exercise questions. The book also provides practical demonstrations on core principles and key behaviors and incorporates a wide range of colorful examples of CFD simulations in various fields of engineering.
In addition, this author:

Introduces basic discretizations, the linear advection equation, and forward, backward and central differences
Proposes a prototype discretization (first-order upwind) implemented in a spreadsheet/MATLAB example that highlights the diffusive character
Looks at consistency, truncation error, and order of accuracy
Analyzes the truncation error of the forward, backward, central differences using simple Taylor analysis
Demonstrates how the of upwinding produces Artificial Viscosity (AV) and its importance for stability
Explains how to select boundary conditions based on physical considerations
Illustrates these concepts in a number of carefully discussed case studies
Essentials of Computational Fluid Dynamics provides a solid introduction to the basic principles of practical CFD
