## What is CFD?

Computational fluid dynamics is an important part of fluid mechanics that deals with the study and analysis of the behavior of fluids and their parameters by using numerical schemes that are processed on a computer. There are other definitions that give us several authors:

An Introduction to Computational Fluid Dynamics The Volume Method (2nd Edition)
by H.K. Versteeg & W. Malalasekera

“Computational fluid dynamics or CFD is the analisys of system involving fluid flow, heat transfer and associated phenomena such as chemical reactions by means of computer-based simulation …”

Computational Fluid Dynamics The Basics with Applications
by John Anderson
“Computational fluid dynamics is the art of replacing of equations the integrals or the partial derivaties (as the case may be) in these equations with discretized algebraic forms, which in turn are solved to obtain numbers for the flow field values at discrete points in time and/or space …”

Essential Computational Fluid Dynamics
by Oleg Zikanov
“CFD (Computational fluid dynamics) is a set of numerical methods applied to obtain approximate solutions of problems of fluid dynamics and heat transfer.”

Numerical Computation of Internal & External Flows
by Charles Hirsch
“Computational fluid dynamics, known today as CFD, is defined as the set of methodologies that enable the computer to provide us with a numerical simulation of fluid flows”

Computational Fluid Mechanics and Heat Transfer
by Richard H. Pletcher, John C. Tannehill & Dale A. Anderson
“The steady advances in computer technology over the past half century have resulted in the creation of a new methodology for attacking complex problems in fluid mechanics and heat transfer. This new methodology has become known as computational fluid dynamics (CFD). In this computational (or numerical) approach, the equations (usually in partial differential or integral form) that govern a process of interest are solved numerically …”
