The invention provides a mixer for a confluent-flow nozzle of a turbine engine, the mixer comprising an annular cap designed to be centered on a longitudinal axis of the nozzle and having a stationary upstream portion and a downstream portion that is movable in rotation about the longitudinal axis relative to the stationary portion, the movable portion of the cap terminating at its downstream end in inner lobes alternating circumferentially with outer lobes, and means for imparting reciprocating rotary motion to the movable portion of the cap. |
