Abstract
A venturi device for a turbine combustor includes a substantially annular outer liner; a substantially annular inner liner; a venturi channel located between the substantially annular outer and inner liners; the substantially annular outer and inner liners being substantially V-shaped in axial cross-section, thereby defining a throat region; the substantially annular outer liner formed with an array of impingement holes and the substantially annular inner liner formed with a plurality of vortex generators facing the substantially annular outer liner.

A venturi device for a turbine combustor comprising:
- a substantially annular outer liner;
- a substantially annular inner liner;
- a venturi channel located between said substantially annular outer and inner liners;
- said substantially annular outer and inner liners being substantially V-shaped in axial cross-section, thereby defining a throat region;
- said substantially annular outer liner formed with an array of impingement cooling holes and said substantially annular inner liner formed with a plurality of vortex generators facing said substantially annular outer liner and said array of impingement cooling holes.
A venturi device for a turbine combustor comprising:
- a substantially annular outer liner;
- a substantially annular inner liner;
- a venturi channel located between said substantially annular outer and inner lines;
- said substantially annular outer and inner liners being substantially V-shaped in axial cross-section, thereby defining a throat region;
- said substantially annular outer liner formed with an array of impingement cooling holes;
- and
- said substantially annular inner liner formed with a plurality of vortex generators facing said array of impingement cooling holes, and a plurality of upstanding fins in said throat region, extending radially outwardly into said venturi channel toward said substantially annular outer liner.
A turbine combustor comprised of a radially inner liner and a radially outer flow sleeve, the radially inner liner parallel with a venturi comprising:
- a venturi device for a turbine combustor comprising:
- a substantially annular outer liner;
- a substantially annular inner liner;
- a venturi channel located between said substantially annular outer and inner lines;
- said substantially annular outer and inner liners being substantially V-shaped in axial cross-section, thereby defining a throat region;
- said substantially annular outer liner formed with an array of impingement cooling holes;
- wherein
- said substantially annular inner and outer V-shaped liners form a plenum chamber closed by another annular member, said outer annular member having one or more apertures therein adapted to supply cooling air to said plenum chamber, and further wherein said venturi channel is open at opposite ends of the venturi channel such that cooling air entering said venturi channel through said one or more apertures flows in opposite directions at said throat region.
