Abstract
An apparatus is provided and includes a turbine including a platform, a casing and a turbine bucket having a hub coupled to the platform and a trailing edge defined relative to a direction of fluid flow through the turbine and a diffuser, defined between a central surface and a downstream section of the casing, which is fluidly coupled to the turbine and disposed downstream from the trailing edge, a slope of the hub being angled by at least 6 degrees relative to a slope of the central surface within about 0.5 turbine bucket chord lengths as measured at the hub from the trailing edge, and the central surface and the downstream section of the casing being at least substantially parallel or divergent from the trailing edge.
