(BQ) Part 2 book "Fundamentals of the finite element method for heat and fluid flow" has contents: Convection heat transfer, convection in porous media, some examples of fluid flow and heat transfer problems, implementation of computer code. | 7 Convection Heat Transfer Introduction In the previous six chapters, the conduction mode of heat transfer has been discussed in detail. Occasionally, convective heat transfer boundary conditions were discussed in these chapters whenever appropriate. However, little information on fluid flow characteristics was given in any of the previous chapters. In the present chapter, the heat transfer mechanism due to a fluid motion is discussed in detail. This method of heat transfer, which is caused by fluid motion, is referred to as heat convection. The study of fluid motion (fluid dynamics) is an important subject that has wide application in many engineering disciplines. Several industries use computer-based fluid dynamics analysis (Computational Fluid Dynamics or CFD) tools for both design and analysis. For instance, aerospace applications, turbo-machines, weather forecasting, electronic cooling arrangements and flow in heat exchangers are merely a few examples. There has been a vast increase in the use of CFD tools in engineering industries in the last two decades, mainly because of an ever-increasing computing power. In the 1980s, a solution for a reasonably sized three-dimensional fluid dynamics problem was rarely possible on a personal computer (PC). However, now it is very common for researchers to solve reasonably sized fluid dynamics problems in three dimensions using such computers. There are several books written on the topic of computational fluid dynamics, which include texts explaining the basic solution scheme underlying a successful CFD software (Cheung 2002; Donea and Huerta 2003; Fletcher 1988; Gresho and Sani 2000; Hirsch 1989; Lewis et al. 1996; Pironneau 1989; Zienkiewicz and Taylor 2000), or books on practical fluid dynamics calculations such as data structure and parallel computing (L¨ hner 2001). Several chapters could be written in the present text on the topic of o CFD alone. However, our main interest is to give a practical introduction to the role of
