Abstract
A turbine scroll for use with an axial turbine is provided. The turbine scroll includes a flow channel, a scroll inlet, a plurality of stator vanes, and a plurality of vane passages. The flow channel is defined by an outer radial wall extending between first and second axial sidewalls that are spaced widthwise apart from one another. The stator vanes are disposed within the flow channel, spaced apart from one another, and are disposed around a circumference of the scroll. Each vane passage is defined between adjacent stator vanes. Each vane passage is open to an outer flow channel portion disposed radially between the stator vanes and the outer radial wall and is open to an annular region disposed radially inside of the stator vanes. The vane passages are configured to direct gas flow in an inwardly spiraling direction.
