Abstract
An article, for example a turbine engine component such as a shroud, airfoil, etc., comprises a wall having a first wall surface subject to a first temperature, for example from the flow stream of the engine. The wall includes a second wall surface, substantially opposite the first wall surface, for exposure to a cooling fluid, for example cooling air. The second wall surface includes a plurality of adjacent ribs protruding from the second wall surface to facilitate transfer of heat from the second wall surface. The ribs comprise a plurality of elongated rib portions each spaced apart one from another across a gap between rib portions, the gaps having a gap length in the range of about 0.002-0.05″.
