DIFFUSING GAS TURBINE ENGINE RECUPERATOR |
| 摘要 |
A method of diffusing and cooling an exhaust flow in an exhaust duct of a gas turbine engine includes circulating the exhaust flow from a turbine section of the gas turbine engine to a recuperator extending within the exhaust duct, circulating air discharged from a compressor section to a combustor of the gas turbine engine through air passages of the recuperator, and cooling and diffusing the exhaust flow by circulating the exhaust flow through exhaust passages of the recuperator having a progressively increasing cross-sectional area and in heat exchange relationship with the air passages. |
