Abstract
In part I of the paper, a control-volume finite-element method for predicting flow and heat transfer through ducts of arbitrary cross sections was described. This paper, part II in the two-part sequence, discusses application of the proposed method to some test problems. Our main interest is in predicting flow through ducts of varying cross sections. However, unfortunately, for ducts of varying cross sections, nothing is available in literature that can be used as a benchmark. This recognition necessitated the adoption of an alternative approach. In this paper, a procedure is described for formulating problems involving flow through ducts of arbitrary cross sections for which the exact solution is known. Such problems, with known exact solutions, then serve as benchmarks to validate the numerical method. Cases considered include a square diffuser and a deforming elliptic duct.
