Seal system including angular features for rotary machine components

摘要

Systems and devices configured to seal interfaces/gaps between stationary components of turbines and manipulate a flow of coolant about portions of the turbine during turbine operation are disclosed. In one embodiment, a seal element includes: a first surface shaped to be oriented toward a pressurized cavity of the turbine; a second surface oriented substantially opposite the first surface and shaped to sealingly engage a contact surface of the static components; and a first set of angular features disposed in the second surface, the first set of angular features fluidly connecting the pressurized cavity and the flowpath of the turbine.

1. A seal element shaped to be disposed between static components of a turbine, the seal element comprising:
a first surface oriented toward a pressurized cavity of the turbine; a second surface oriented substantially opposite the first surface and shaped to sealingly engage a contact surface of the static components; and an angular feature disposed in the second surface, the angular feature having a first angled portion fluidly connected to the pressurized cavity of the turbine, and a second angled portion fluidly connected to the first angled portion and a flowpath of the turbine to fluidly connect the pressurized cavity and the flowpath of the turbine, wherein the first angled portion and the second angled portion are shaped to alter a direction of a flow of pressurized coolant through the angular feature, and wherein the angular feature is shaped to accelerate the flow of pressurized coolant from the pressurized cavity to the flowpath of the turbine.
