Computational Fluid Dynamics

Chapter 4 CFD Techniques—The Basics

4.1 INTRODUCTION

Some of the basic computational techniques that are required to solve the governing equations of fluid dynamics are examined in this chapter. The authors will endeavor to demonstrate how these techniques are employed to obtain an approximate solution for the governing equations of flow problems with appropriate boundary conditions applied for the specific problem considered.

The process of obtaining the computational solution consists of two stages. The first stage involves the conversion of the partial differential equations and auxiliary (boundary and initial) conditions into a system of discrete algebraic equations. This first stage is commonly known as the discretization stage.
