Shear jet cooling passages for internally cooled machine elements

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