Abstract: A shroud segment that includes a body including a leading edge, a trailing edge, a first side edge, a second side, and a pair of opposed lateral sides. A first lateral side is configured to interface with a cavity having a cooling fluid, and a second lateral side is oriented toward a hot gas flow path. The shroud segment includes a first channel disposed within the body having a first end portion and a second end portion and a second channel disposed within the body having a third end portion and a fourth end portion. The first and second channels are configured to receive the cooling fluid from the cavity to cool the body. The first end portion and the fourth end portion each include a hook-shaped portion having a free end.

Abstract: A shroud segment for use in gas turbines, includes a body, leading edge, trailing edge, a first and second side edge, and a pair of opposed lateral sides between the leading and trailing edges and the first and second side edges. A first lateral side of the lateral sides interface with a cavity having a cooling fluid. A second lateral side interfaces with a hot gas flow path. A first channel disposed within the body includes a first and second end portion. A second channel is disposed within the body includes a third and fourth end portion. The first and second channels receive the cooling fluid from the cavity to cool the body. The first and fourth end portion have portions with free ends having a width greater than an adjacent portion coupled to the free end.
