    摘要: The present invention relates to a turbine assembly having an aerofoil and/or an end wall each having an outer surface with a structure for directing a flow of a cooling medium at the outer surface. The structure at the outer surface has at least a first groove and a second groove extending in the outer surface from a leading to a trailing edge and being oriented in at least two different directions with a deflection angle (α) towards each other, with the deflection angle (α) having a component in a span wise direction of the aerofoil. The structure at the outer surface of the end wall has at least a first groove and a second groove extending in an axial direction of the turbine assembly, matching an outer profile of the aerofoil and oriented in at least two different directions with a deflection angle (α) towards each other.

    摘要: A flow machine is described having a first space adapted to contain a hot fluid and delimited by a wall. The wall having a first wall surface facing the first space and a second wall surface turned away from the first space. Cooling is provided for a region of the wall by supplying a relatively cool fluid onto the second wall surface. The cooling means includes a supply chamber containing the second fluid, a cavity adjacent the second wall surface, at least one duct, which has an inlet opening at the supply chamber and an outlet opening at the cavity for conveying the cool fluid to the cavity, and a deflection surface facing the cavity.

    摘要: A turbine arrangement with a rotor and a stator surrounding the rotor forming a flow path for hot and pressurized combustion gases between the rotor and the stator is provided. The rotor defines a radial direction and a circumferential direction and includes turbine blades extending in the radial direction through the flow path towards the stator. The turbine blades have shrouds located at their tips and the stator includes a wall section along which the shrouds move when the rotor is turning. A supersonic nozzle is located in the wall section and is connected to a cooling fluid provider. The supersonic nozzle provides a supersonic cooling fluid flow towards the shroud. The supersonic nozzle is angled with respect to the radial direction towards the circumferential direction in such an orientation that the supersonic cooling fluid flow has a flow component parallel to the moving direction of the shroud.
