<p>A turbine section having a seal cavity with effectively continuous flow surfaces is disclosed. Various construction details are developed which disclose a fluid cooled stator assembly having a plurality of ejectors for flowing cooling fluid into the seal cavity. In one embodiment, the ejectors (114) include a wall (132) which have circumferentially spaced mating edges (134, 136) arranged in a cascade type configuration. The arrangement of the walls provides an effectively continuous flow surface for the radially flowing annulus of cooling fluid within a seal cavity (108). In an alternate embodiment, an opening (152) between adjacent mating edges (154, 156) provides access to mechanical fasteners (162) which retain a sealing shroud (164) to a stator assembly (150).</p> |
