A numerical study of the effect of using double lateral sub-holes at different span-wise angles on flow structure and film-cooling performance is performed. The lateral angles for each sub-hole change from 10° to 20° at the same film-hole diameter (12.7 mm) and jet angle (35°). The flow-field analys...
