Özet
In this study, the effects of heat transfer in turbulent flow fields of impinging slot jet confined by inclined plates were investigated experimentally. Temperature distributions on the impingement plates were obtained with thermal camera. Temperature measurements were carried out on the impingement plate in four different impinging slot jet flow setups confined by plates with inclination angles of ? = 0°, 15°, 30°, and 45°, with an interplate spacing of 0.5 ? H/W ? 6, and a Reynolds number range of 10,000 ? Re ? 30,000. The effects of confinement plate inclination angle, intervals between the plates, and Reynolds number on the Nusselt number distributions of the impingement plates were examined. It was observed that Nusselt number values increased with increasing Reynolds number and decreased with increasing intervals between the plates. There are secondary top points in the Nusselt number distributions on the impingement plate for low inclined confinement plates (? = 0° and ? = 15°) and small interplate spacings (H/W = 0.5 and H/W = 1), while there is an increase in the Nusselt numbers at the ends of the impingement plate for high inclined confinement plates (? = 30° and ? = 45°) and small interplate spacings (H/W = 0.5 and H/W = 1).
