description Embodiments of the invention relate generally to rotary machines and, more particularly, to the reducing mixing of packing leakage and the main flow of hot gas or steam in gas and steam turbines, respectively. In one embodiment, the invention provides a turbine bucket (140) comprising: a platform (142) portion; an airfoil (150) extending radially outward from the platform (142) portion; and at least one recess (194) extending radially inward into the platform (142) portion, the at least one recess (194) being disposed at an angle relative to a leading edge of the platform (42) portion.
