Abstract

In this chapter the modeling of a gas-fired single-ended radiant (SER) tube is presented in full detail. The physical processes and models widely include turbulence, flow relaminarization, partially premixed combustion, radiation heat transfer, near-wall phenomena, dimension reduction modeling etc. The focus of this chapter, however, is not the SER tube modeling but the demonstration of the methodology, modeling effect assessment and problem-solving techniques that can be widely applied in numerical simulation. This chapter also demonstrates a few possible means to simplify or decompose a complex modeling problem into a number of smaller but easier modeling tasks as well as possible means to make the best use of the available computational resources for achieving optimized modeling results.
