A sealing element for sealing a component gap with respect to a flow, in particular for use in a fluid-flow machine, specifically in a turbomachine is provided. In addition a fluid-flow machine is provided including such a sealing element for sealing a component gap. The sealing element includes a hollow profile enclosing a cavity. Arranged in the hollow profile are a first opening and a second opening, which are spaced apart from each other in the longitudinal direction of the hollow profile. The first opening is formed as an inlet opening for a cooling fluid into the cavity of the hollow profile, the second opening is formed as an outlet opening for the cooling fluid from the cavity of the hollow profile. With the sealing element arranged in a fluid-flow machine, the sealing element can consequently be internally cooled by means of the cooling fluid. Furthermore, the sealing element uses the pressure gradient occurring in the flow in the direction of flow to form a stable cooling fluid flow.
A sealing element for sealing a component gap in a fluid-flow machine with respect to a flow carried in a flow channel, the sealing element comprising:
A sealing element for use in a flow channel having at least one delimiting wall and receiving a flow of a working fluid, wherein the flow of the working fluid flow has a pressure gradient in a direction of flow and the delimiting wall includes a component gap having at least two gap side faces, the sealing element comprising:
A fluid-flow machine comprising:
