Abstract (en)
An internally-cooled turbomachine component, comprising a main body (200) comprising a first end wall (210), a second end wall (212) spaced apart from the first end wall (210), and a sidewall (220) which extends between the first end wall (210) and the second end wall (212) such that the first end wall (210), second end wall (212) and sidewall (220) define a cooling passage (230) extending between a fluid inlet (202) and a fluid outlet (204), a pedestal bank (240) comprising a plurality of pedestals (241) which span the cooling passage (230) between the first end wall (210) and the second end wall (212), wherein the pedestal bank (240) is spaced from the sidewall (220) to define a flow channel (250) therebetween; and a low-rise turbulator (260) located in the flow channel (250), wherein the low-rise turbulator (260) extends partway between the first end wall (210) and the second end wall (212).
