...Nicholas E. Holgate; Peter T. Ireland; Eduardo Romero A novel airfoil leading edge film cooling design has been investigated, and its performance over conventional alternatives quantified. In conventional designs, the region near the geometric stagnation line is typically between the two most...

... of the effects of mainstream flow turbulence on film effectiveness have been conducted on both flat plates and vane leading edges. The film cooling holes investigated were frequently within a range of blowing ratio and surface angle parameters conducive to good surface attachment of the coolant jets...

..., and 40,000, Ro = 0.2, 0.4, and 0.6) were numerically explored. The selected geometry (a smooth radial channel) is rather simplified compared to modern leading edge cooling cavities, which are characterized by the adoption of jet impingement cooling and film cooling holes (see Elebiary and Taslim [ 12...
