Investigation of the Effect on Heat Transfer and Flow Characteristics of Circular Impingement Jets in a Rectangular Duct

EasyChair Preprint 8500

Abstract

In the study, it was investigated air in rectangular channel with jet impingement. It was examined numerically air flow under constant inlet temperature, and constant target surface wall boundary condition. All analyzes have been carried out by using Ansys Fluent software. It was used SST k-w turbulent model in the study. Basic parameters of the study is nozzle spacing, jet diameter, Reynolds number, Nusselt number, and pressure difference. It was examined turbulent air flow in the range of 15000Re≤35000. On the other hand, it was discussed flow behavior in the rectangular channel and local Nusselt number. As a result, it was observed that finding obtained compatible with well-known correlations. Average Nusselt number increased with increasing Reynolds number and decreasing target surface-to-nozzle spacing. In addition to, pressure difference increase logarithmically with Reynolds number.
