Abstract: A core for use in cooling a component used in a rotary machine is provided. The core includes a passage including a divider separating a first inlet portion and a second inlet portion to define a split pass inlet, which is fluidly coupled to at least one first pass, at least one second pass, and at least one turn. The at least one first pass channels a flow of cooling fluid in a first direction from the split pass inlet. The at least one second pass channels the flow of cooling fluid in a second direction opposite the first direction. The at least one turn changes a direction of flow of the cooling fluid from the first direction to the second direction. The at least one first pass, the at least one second pass, and the at least one turn are arranged, such that the passage defines a serpentine passage.
