The invention relates to a method of mixing in a discharge conduit, in a turbine engine with two or more flows, of a primary flow and a secondary flow, the two flows emerging in said discharge conduit by two coaxial ducts, separated by an internal housing which has an end downstream relative to the flow direction of the flows, the two coaxial ducts each being defined between an internal wall and an external wall, upstream of the downstream end of the internal housing, and the secondary flow surrounding the primary flow, characterised in that it consists of disposing at least one divergent radial deflection means in primary duct, spaced apart from the walls of said primary duct. It likewise relates to the deflection means capable of implementing the method, the fixing means of said deflection means being capable of positioning them in the primary duct; as well as a turbine engine equipped with these means, comprising at least one primary flow and one secondary flow, the two flows emerging in a discharge conduit by two coaxial ducts, the secondary flow surrounding the primary flow.
Method of mixing in a discharge conduit, in a turbine engine with two or more flows, of a primary flow and a secondary flow, the two flows emerging in said discharge conduit by two coaxial ducts, separated by an internal housing which has an end downstream relative to the flow direction of the flows, the two coaxial ducts being defined upstream of the downstream end of the internal housing by a primary duct in which the primary flow circulates and a secondary duct in which the secondary flow circulates, the secondary flow surrounding the primary flow, the method consisting of disposing at least one divergent radial deflection means in the primary duct, spaced apart from the walls of said primary duct.
Method of mixing according to the preceding claim, wherein an alternation is organised, azimuthally around the axis of the ducts, of zones where the primary flow is deflected and zones where it is not deflected.
Turbine engine with two or more flows, comprising at least one primary flow and one secondary flow, the two flows emerging in a discharge conduit by two coaxial ducts, separated by an internal housing which has an end downstream relative to the flow direction of the flows, the two coaxial ducts being defined upstream of the downstream end by a primary duct in which the primary flow circulates and a secondary duct in which the secondary flow circulates, the secondary flow surrounding the primary flow, said turbine engine being equipped with a device including at least one divergent radial deflection means disposed in the primary duct, spaced apart from the walls of said primary duct, the device also including at least one fixing means capable of positioning said deflection means in said primary duct.
