...Farah Nazifa Nourin; Ryoichi S. Amano Multiple jet impingement cooling plays a significant role in the leading-edge cooling of the gas turbine blade. The heat transfer enhancement with this method depends on stand-off distance, nozzle array arrangement, surface roughness, a dimpled surface...

...Farah Nazifa Nourin; Ryoichi S. Amano In this study, the internal cooling channel was investigated without any bend. Smooth surfaces and dimpled surfaces were investigated using the different combinations of connecting circular and rectangular holes. The computations were performed using the large...
