Disclosed is an exhaust mixer ( ) including a passage ( ) extending from an inlet ( ) to an outlet ( ) that is coincident with a centerline axis of mixer ( ). Several ridges ( ) are circumferentially disposed about the axis and each flare away from the centerline axis relative to a direction along the centerline axis from inlet ( ) toward outlet ( ). Ridges ( ) each define a corresponding one of several inner channels ( ) radially disposed about passage ( ) that each intersect passage ( ) between inlet ( ) and outlet ( ). Several outer channels ( ) are also radially disposed about passage( ) and are each positioned between a corresponding pair of inner channels ( ). Ridges are each shaped to turn inner channels ( and outer channels ( ) about the axis as ridges ( ) extend along the indicated direction. Inner channels ( ) diverge away from the axis and one another in this direction while outer channels ( ) converge toward the axis and one another in this direction.
