Abstract:
1. A device for mixing at least two separate fluid flows having a plurality of fluid flow channels arranged in a plurality of concentric rings with respect to a longitudinal center line, the fluid flow channels forming first rings, in which the fluid flow channels are inclined in a first direction in the circumferential direction with respect to the longitudinal center line, in such a way that as medium flows through them, they in each case generate an annular swirl flow rotating in the first direction for each first ring, the fluid flow channels forming second rings, in which the fluid flow channels are inclined in a second direction which is counter to the first direction, in the circumferential direction with respect to the longitudinal center line, in such a way that, as medium flows through them, they in each case generate an annular swirl flow rotating in the second direction for each second ring, first groups, each comprising at least one first ring, and second groups, each comprising at least one second ring, alternating in the radial direction with respect to the longitudinal center line, wherein the inclination of the channels with respect to the longitudinal center line increases at increasing distance from the longitudinal center line;
