Chapter One - Trends, Tricks, and Try-ons in CFD/CHT

Abstract Computational fluid dynamics and its counterpart computational heat transfer are subjects that inspire alarm in precomputer-trained professors and awe in young would-be researchers. One aim of this chapter is to diminish these reactions by clarifying both the laudable and the debatable natures of the subjects. A second aim is to make clear, to those who are not overanxious to follow fashion, that there remains much scope for valuable innovations. The chapter reviews items selected from approximately half a century of three-steps-forward-two-steps-back actions, and it contains such adumbrations of detail and expressions of personal opinion as its author judges to be conducive to its aim.
