ABSTRACT:
A cooling passageway construction particularly adapted for cooling the interior of a heated turbine engine assembly and/or airfoil blade includes an undulating partition which subdivides the passageway into first and second subpassages. The partition defines localized minimum throat areas within each subpassage to produce localized shear jet flow between the partition and the walls of the passageway. Bleed holes may be formed through the partition to generate additional turbulence within the coolant flow and further enhance heat transfer.
