Abstract
A two-dimensional jet-impinged on a target plate vertically placed for the jet axis. The target plate was mounted at a distance from the jet exit of 3 times the jet slot width. A circular cylinder was installed on the jet central plane between the target plate and the jet exit. Characteristics of flow field and heat transfer in changing the diameters and the locations of the circular cylinder were examined. The maximum local Nusselt number attained around the stagnation point was augmented by about 76% and the average Nusselt number increased by about 30% compared to the ones for normal impinging jet without the insertion of a cylinder.
