Abstract
A transition nozzle is provided and includes a liner in which combustion occurs and through which products of the combustion flow toward a turbine bucket stage. The liner includes opposing endwalls and opposing sidewalls extending between the opposing endwalls. The opposing sidewalls are oriented to tangentially direct the flow of the combustion products toward the turbine bucket stage. At least one of the opposing endwalls and the opposing sidewalls including a flow contouring feature to guide the flow of the combustion products.
Claims20
A transition nozzle, comprising:
- a liner in which combustion occurs and through which products of the combustion flow toward a turbine bucket stage,
- the liner including opposing endwalls and opposing sidewalls extending between the opposing endwalls,
- the opposing sidewalls being oriented to tangentially direct the flow of the combustion products toward the turbine bucket stage, and
- at least one of the opposing endwalls and the opposing sidewalls including a flow contouring feature to guide the flow of the combustion products.
A transition nozzle, comprising:
- a liner having a first section in which combustion occurs and a second section downstream from the first section through which products of the combustion flow toward a turbine bucket stage,
- the liner including, at the second section, opposing endwalls and opposing sidewalls extending between the opposing endwalls,
- the opposing sidewalls being oriented to tangentially direct the flow of the combustion products toward the turbine bucket stage, and
- at least one of the opposing endwalls and the opposing sidewalls including a non-axisymetric flow contouring feature to guide the flow of the combustion products.
A gas turbine engine, comprising:
- a compressor having an outlet through which compressed flow passes;
- a combustor stage coupled to the outlet, the combustor stage being receptive of the compressed flow and including a combustor in which combustible materials are mixed and combusted with the compressed flow to produce exhaust;
- and
- a turbine coupled to the combustor stage, which is receptive of the exhaust produced in the combustor for power generation,
- a portion of the combustor being oriented tangentially with respect to an engine centerline and including a non-axisymetric flow guiding feature.
