1. A nacelle assembly for a turbine engine comprising:
a nacelle housing surrounding a core engine and a propulsor section;
a condenser assembly supported at least partially within the nacelle housing, the condenser assembly configured to recover water from a core gas flow generated by the core engine;
an exhaust duct extending between the nacelle housing and the core engine, the core gas flow is directed radially outward through the exhaust duct to the condenser assembly; and
an evaporator assembly supported at least in part within the nacelle housing and in thermal communication with at least a portion of the exhaust duct where heat from the core gas flow is utilized to heat a water flow to generate a steam flow injected into the core flow path, wherein the exhaust duct comprises a plurality of passages with each including a radial portion where the core gas flow is directed radially outward to the condenser assembly, a circumferential portion in thermal communication with the evaporator assembly, and an outlet communicating the core gas flow to the condenser assembly.
