Abstract: The disclosure includes a sealing assembly for a turbine system. In one embodiment, the sealing assembly is for a turbine having a rotor blade and a stator nozzle. The sealing assembly includes a pair of oppositely facing seal teeth including concave surfaces. The pair of oppositely facing seal teeth are positioned on one of the rotor blade and the stator nozzle, and are for sealingly engaging the other of the rotor blade and the stator nozzle during operation of the turbine.

Abstract: Systems and methods Embodiments for facilitating onboarding of a cooling fluid are disclosed herein. According to one embodiment, a system may include a rotor assembly, a wheel space cavity adjacent to the rotor assembly, and a bucket shank cavity in fluid communication with the wheel space cavity. The system may also include at least one protrusion disposed on the rotor assembly in the wheel space cavity. The at least one protrusion may be configured to direct the cooling fluid radially from the wheel space cavity to the bucket shank cavity to minimize pressure loss in the cooling fluid.
