Computational fluid dynamics (CFD) is a computer simulation technique to describe, evaluate, and predict the motion of fluid within a domain of interest. This chapter provides an overview of CFD, the brief history behind it, available packages and codes, basic workflow of a typical CFD job, and some discussion on the challenges and opportunities for the CFD community in general and the uniqueness of its application in the water and wastewater treatment industry. Most of the application-oriented CFD software is mesh-based, which means that the simulation domain is divided into discrete cells, elements, or grid points. The name of the discrete unit depends on the numerical method to be used, which include finite volume method, finite element method, and finite difference method corresponding to cells, elements, and grid points, respectively. The chapter also presents a brief introduction of these methods.
