FIELD: process engineering.
SUBSTANCE: invention relates to static mixers and may be used for mixing gases, for example, waste gas with secondary gas. Static mixer 1 comprises two vanes (2; 2a, 2b) to swirl flow 4 in channel. Vane front edges on ingoing glow side are arranged perpendicular to channel flow and parallel with channel height 10. Surfaces downstream of said flow are concaved in opposite directions. Every said vane 2a, 2b represents an aerodynamic element with face wall 20, convex sidewall 21, and concaved sidewall 22. Vane cross sections perpendicular to sidewalls feature the same shapes that aircraft bearing surface cross sections have.
EFFECT: lower pressure losses in flow and decreased structure vibrations.
