Abstract:
1. A rotating machine, comprising: a first machine portion; a second machine portion; and a rotating machine portion connecting the first machine portion to the second machine portion; wherein the rotating machine portion comprises a rotating shaft including one or more cooling channels for providing cooling air to the second machine portion; wherein one or more particle separation slots fluidly connect one or more of the one or more cooling channels to a cavity, the particle separation slots being arranged and disposed to facilitate flow of a portion of the cooling air from the first machine portion to the cavity and to urge particles into the particle separation slots in the same direction as the flow of the portion of the cooling air toward the cavity, the flow of the particles being by centrifugal forces and the centrifugal forces being provided by the rotating machine portion; and wherein the one or more particle separation slots divert between about 1 vol. % and about 10 vol. % of cooling fluid from the one or more cooling channels, a remaining portion of the cooling fluid flowing toward the second machine portion.
