Abstract: In this paper direct measurements were made to investigate the water jet impingement at the higher temperature curved surface. Heat transfer coefficient at the stagnation point and local area was obtained through the experimentation.The effects of jet impingement exit velocity,nozzle-to-surface spacing and other correlative parameters were investigated in detail.The result showed that the heat transfer coefficient at the stagnation point was higher than at other areas,and it decreased with increasing X/D, but increased with increasing exit velocity.The nozzle-to-surface spacing showed some effect on heat transfer coefficient at a lower exit velocity.
