Özet
This study aims to numerically investigate the influence of surface radiation on jet impingement cooling of a two-dimensional concave surface with a slot nozzle. For a constant value of the aspect ratio (h/2W=4.0), varying values of Reynolds number (Re=1185, 2370, 3555 and 4740) and surface emissivity (epsilon=0.05, 0.45 and 0.90) are tested. The cases with or without radiation are comparatively examined. The results are presented as the local temperature variations as well as the variations of the convective and radiative Nusselt numbers, Nusselt number ratio and total Nusselt number. It is disclosed that the increase in surface emissivity improves the overall cooling performance.
