CHAPTER OBJECTIVES • To introduce the techniques for computational solutions of the fluid dynamic equations of motion • To describe the finite-difference and finite-element formulations
• To specify finite-difference and finite-element equations for incompressible viscous flow • To illustrate use of these equations via example calculations
10.1. INTRODUCTION Computational fluid dynamics (CFD) is a science that, with the help of digital computers, produces quantitative predictions of fluid-flow phenomena based on the conservation laws (conservation of mass, momentum, and energy) governing fluid motion. These predictions
