Abstract

In the present study, turbulent flow passing over a four-row finned tube heat exchanger has been simulated by nine different turbulent models. Annular fin has a complex geometry and as a result, very complex phenomena such as flow separation, horseshoe vortices, generated wakes, etc. may be observed. Results have been compared with experimental correlations and in more detail to each other. In addition, capability of numerical models as a flow visualization tool, their strengths and weaknesses have been studied.
