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 notch includes a forward surface extending 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 notch also includes an aft surface extending from the forward surface to the wall second side which is inclined at an acute discharge angle relative to the second side. The holes are disposed at an acute discharge angle relative to the second side for discharging the first fluid into the notch, and the notch discharge angle is smaller than the hole discharge angle for discharging the first fluid from the notch along the second side.
