An apparatus for improving heat transfer through a leading portion of an aircraft engine. The apparatus includes a wall that is defined by the leading portion. A surface is defined by the wall and the surface defines a channel through the leading portion of the aircraft engine. A source for a fluid that is fluidly connected to the channel. Pits are defined in the surface of the channel such that the bleed air can flow across the pits.
