A wall adapted for use in a gas turbine engine between a first and a hotter second fluid includes a first side over which is flowable the first fluid, and an opposite second side over which is flowable the second fluid. An elongate slot extends inwardly from the second side and is disposed in flow communication with a plurality of longitudinally spaced apart holes extending inwardly from the first side. The holes are disposed at a compound angle relative to the second side for discharging the first fluid obliquely into the slot and at a shallow discharge angle from the slot along the second side. In a preferred embodiment, the slot has an aft surface including a plurality of longitudinally spaced apart grooves extending from the holes to the wall second side.

A wall adaptable for use in a gas turbine engine between a first fluid and a second fluid being hotter than said first fluid, comprising: a first side over which is flowable said first fluid; an opposite second side spaced from said first side along a transverse axis and over which is flowable said second fluid in a downstream direction along an axial axis disposed perpendicularly to said transverse axis; an elongate slot extending partly inwardly along said transverse axis from said second side toward said first side and longitudinally along a longitudinal axis disposed perpendicularly to both said transverse axis and said axial axis; a plurality of longitudinally spaced apart metering holes extending partly inwardly from said first side toward said second side, and disposed in flow communication with said slot for channeling thereto said first fluid; and said holes being inclined along centerlines thereof at a compound angle relative to said second side for discharging said first fluid obliquely into said slot and at a shallow first discharge angle from said slot along said second side into said second fluid for film cooling said wall second side.
