What Is C++?

Abstract

Publisher Summary This chapter focuses on computational fluid dynamics (CFD). The array of examples illustrates how computational fluid dynamics has evolved through decades of rigorous development of numerical techniques. {CFD} computation involves the generation of a set of numbers or digits that provides a realistic approximation of a real-life fluid system. The main benefit of learning {CFD} is to gain experience and a thorough understanding of the flow physics, and the fundamentals of the numerical techniques and models. Additionally, practical guidelines for good operating practice are needed to increase competency in the use of this powerful tool. This chapter addresses all of the aforementioned issues to better equip the reader with the necessary background material for a good understanding of the internal workings inside a {CFD} code, and its successful operation. More recently, {CFD} is revolutionizing the teaching and learning of fluid mechanics and thermal science in higher education institutions through visualization of complex fluid flows. Development of some CFD-based educational software packages such as FlowLab by {ANSYS} have allowed students to visually reinforce the concepts of fluid flow and heat transfer through a “Virtual Fluids Laboratory.” This software also allows teachers to create their own examples or customize predefined existing ones. Using carefully constructed examples, students are introduced to the effective use of {CFD} for solving fluid-flow problems and can instinctively develop an intuitive feel for the flow physics.
