Source Code for "Principles of Computational Fluid Dynamics" CFD BOOK

The source code for "Principles of Computational Fluid Dynamics" serves as an essential resource for researchers and students in computational fluid dynamics. This repository contains implementations of fundamental CFD algorithms including finite difference methods, pressure-velocity coupling schemes (such as SIMPLE algorithm), and turbulence modeling approaches. The codebase demonstrates practical application of numerical discretization techniques, boundary condition handling, and convergence criteria for solving Navier-Stokes equations. Researchers can utilize this well-structured code as a foundation for developing advanced simulations, with modular components that allow easy integration of custom turbulence models or multiphase flow implementations. Students can study the code architecture to understand key programming patterns in scientific computing, including matrix solvers, time-stepping methods, and parallel computation techniques. The commented source files provide clear explanations of algorithmic choices and numerical stability considerations. By offering access to these verified implementations, the resource enables practical experimentation with different discretization schemes (central difference, upwind, hybrid) and facilitates understanding of mesh generation, flux calculation, and post-processing methodologies. The code supports learning about implementation details for common CFD challenges including handling of compressible flows, implementation of various boundary conditions, and visualization of results.
