| Abstract | ||||
| The heat transfer characteristics in a stagnation region were investigated experimentally for a five circular free jets impinging into a heated flat plate. The local temperature distribution, on a thin flat plate was measured using thermal infrared camera. To get precise heat transfer data over the plate, fully developed straight pipe jets were used in this study. Mean jet Reynolds number varies from 1000 to 45000 and vertical distance jet-to-plate, H/D, from 2 to 6, while the spacing jet-to-jet is, S/D, varies from 2 to 8. A geometrical arrangement of one jet surrounded by four jets in -line array was tested. | ||||
